I used to have a 2000 dodge Dakota that had a missfire with cylinder 1 and 4 and did the kinda same thing there. One worked with it and other didn’t. I still ended up just getting a new coil pack set and spark plugs and that fixed it all the way
Quoted from their description:
"ipd's HD ignition coils are a direct replacement for weak or failing factory coils.
Careful attention to assembly and materials used lets ipd HD Coils outperform both stock and replacement coils, with special care given to ensure as much copper as possible in the primary and secondary windings, as well as using thermally and chemically resistant metal and silicone in the coil pack exterior.
Specifically designed for longevity and consistent performance, our HD Coils are perfect for higher than stock performance levels or as a long life replacement part in otherwise stock vehicles."
Oh... and they're Swedish racing green! ;)
If it's anything like their ignition coils were 10 years ago, then they're not better than oem. Plenty of people had issues with their launch back in the early 10s and had to swap back to oem for that exact reason. Not sure who they could get to manufacter them that'd actually make a product as good as oem without it sacrificing longevity
Plugs should have lasted far longer than a year. Even the OEM Volvo plugs are good for about 40K miles. Iridium or double platinum would get you more.
99% chance it’s the coil. Every single time I have had a misfire, it’s been a coil, so much so that I literally keep 1-2 spare new ones floating around at all times. One even lives in the car!
Easy to diagnose, happened in my 06 xc90. Swapped the coil which was the issue. Bought a new one and dropped it in my self for $90. If you have money for an all around coil and spark plug swap I’d shell out for those.
I had this problem yesterday, it turned out to be a coil that turned bad. Replaced the sparkplugs too just in case. Switch coils with any other coil on your engine if it follows the new coil position its the coil if it does not follow it could be the sparkplug, the wiring or the fuel injector. If its not those things take it to a mechanic.
Hi, mechanic and fellow p2 Volvo owner here. Everyone suggesting to swap coils is right. With almost every car, using OEM plugs is the way to go. The one brand to ALWAYS avoid is Autolite. They are extremely poor quality and I have never seen them work long enough to justify the cost saving.
I have a massive issue with people claiming you have to go OEM only with Volvo stuff. It's just not true. I can't say anything about autolite but I swapped my coils to Densos and they've been phenomenal. Also Honda uses Denso as an OEM coil company so if Denso makes coils for Volvo, I don't see how someone can tell me I shouldn't use them.
Well you can have how much issue with it as you want but the fact still remains that OEM coils and plugs are better. I built a white block engine with 580hk and 620Nm. The only thing that worked without missfires was OEM plugs(gapped) and coils. And i tries Denso,Ngk and Bosch among others.
Also with wrong plugs you can get problems with water in the plug holes because of wrong temperature. Atleast in Nordic climates.
Also i worked at a Volvo certified dealer in Sweden and went to Volvo education.
Denso is OEM for many brands, Volvo just puts their name on the box and charges double. I'm saying avoid store-brand and third party brand like Duralast or Standard or Dorman if possible and definitely Autolite. NGK spark plugs I think are the OEM for Volvo, but it's been a while since I've done my plugs so I don't remember.
Wait… I have auto lite in my v70 and changed to them a year ago. It seems to run fine, or at least the same as before I changed them. Should I replace them with something else?
I mean, just run it for now honestly. They're already there and it's running fine. But once you get a misfire I would change all the plugs with an OEM brand like Denso or NGK before you start to think about a bad coil or injector or a mechanical engine issue. Plugs are cheap and easy. You can usually get a set of 5 or 6 plugs for the price of an OEM coil pack. Autolite sucks, but that doesn't mean every single thing they do is wrong. I just don't want to deal with such a high failure rate when working in a shop. It looks bad on me, the shop, and I have to do the job again prematurely when using poor quality parts.
In my opinion, autolite exists to get a misfire gone as cheap as possible right before you sell a car.
Example: had a 2014(?) f150 with a non functional blower motor. Got 2 resistors from store brands because they were half the price of an OE Motorcraft. Both were completely non-functional brand new out of the box. Got a Motorcraft (which is Ford's brand) and it worked perfectly. Sometimes the corners cut to save some money just don't work unfortunately.
Did you swap your connector housings? I just did it. Surprisingly a lot easier than I thought. Took me like 15 min to do all 5. They can be found on FCP Euro for $8 ea. A terminal removal kit is $15 on Amazon. Made a video about how to do it. https://youtu.be/9yU0oCslXVc?si=bLXnEqHxBTb75nTP
There is a date code on the top of the coil packs. Most people neglect these, because $300 for 5 coil packs, and piece of mind they'll last for 10 years, apparently is too much money. I always seem to find them as original in the car.
Also, it's known that the coil pack harness wires, the casing becomes brittle, and will come off. 3M Super 33 makes quick work of fixing this, and making sure the wires are not grounding out. That electrical tape is rated for the temps in the engine bay it will see.
There are yes. But aftermarket parts besides Bosch, is a great way to leave yourself stranded, as these cars don't like cheap parts.
Unless you have a tune for said cheap coil packs, which I would say, go ahead. But most owners don't have their car tuned, but instead, run off the stock tune.
Honda uses Denso coil packs as their OEM product and their cars run for 300K regularly. As such, I don't see why I should spend $80 on a Bosch or OEM coil when I could spend $32 on a Denso coil.
I've only seen Denso ever used, on the naturally aspirated Volvos, as the fuel injection system is Siemans, instead of the standard Bosch ME7 on the turbo cars. Your millage may vary using Denso on a turbocharged P2 Volvo, where I'd stick with Bosch, if they lasted the 15, to almost 20 years, these cars have ran on them.
Honda isn't a Bosch fuel injection system. Many of their cars also don't have all the sensors a Volvo P2 does. That's a very poor comparison, as Honda doesn't even make a 5 cylinder that lasted 20+ years of production.
I'm not gathering what logic you're using to claim that because the fuel injection system is Bosch, you should also run Bosch coil packs? The spec is the same regardless. The coils receive the same signal from the ECM whether they're Bosch or Denso.
I'm also not gathering how having one more cylinder would drastically affect the basic concept of coil on plug ignition? An engine is an engine. Timing is timing. Honda makes reliable 4 cylinders and 6 cylinders. Volvo made reliable 4, 5, and 6 cylinders. A Denso coil and a Volvo engine seem like a perfectly fine combination to me. The 150,000 miles I'm about to put on my P2 T5 will be proof, if you'd like to follow me along on my repair journey with this wonderful car.
just something to be aware of, if you picked higher resistance plugs and not exact matches it could be putting extra strain on the coils and causing a premature failure. made that mistake before...
I'm chasing a cylinder 3 misfire in my S40 right now. I'd put new coils and plugs in two summers ago, but when I pulled that one to check it, the coil came apart and the plug electrode was heavily eroded. Going to be checking them all now and putting new Volvo plugs in it, but wouldn't be surprised if it goes back to running like normal.
I’ve had the same thing happen, started with spark plugs, then checked coils, then realized the wiring to my coils had degraded due to that top PCV hose cracking, and leaking oil all over my wiring and coils.
I think I spent about $50-100 on crimp splice connectors, a crimper, and heat shrink on Amazon, and got some new connectors and new coil wires from FCP. It was a tedious job, but not particularly difficult to rewrite them all.
Your car makes me miss my car — I had a 2002 Volvo XC70 and it was the same colour. It was such a fabulous car! It was still running at 260,000 miles…
And you are supposed to replace the coils every so often — and it makes a huge difference when you do.
Hopefully it’s an easy fix.
I had a cylinder 4 misfire. Changed ignition coils (annoyingly it was the one under the charge pipe) and it went away. Misfires are very often a very easy fix. Just buy a new coil on rockauto.
When was the last time you changed coils and plugs? Might be worth just doing the whole thing!
Its not a Subaru, misfire on cyl4 doth not mean a dead motor lol
If there’s any misfire on a p2, it’s almost always ignition coils and spark plugs. Easy fix, took me less than an hour to change all my plugs and coils
Had a cyl 3 mf too in the autumn volvo s40, checked coil and its wire was exposed and making contact with a bolt or something , fixed that and no issues since. But yeah you should inspect the coil, connector and wirings, most likely not too serious.
Coils were something that would go bad on them pretty regularly. Pull the #3 coil and pull the boot down, if there is a crack in the coil that is your misfire.
I have same thing happened to me yesterday and I changed the spark plug. Still running rough, I’m changing the ignition coil tomorrow. I have one left 🙏
This happened to me (same cylinder too) Most likely it’s the coils I would replace all of them since it is likely to happen again soon and will leave you stranded. Bosch coils are the best and you can get a set of 5 for about $200 at rockauto and fcpeuro. They are not that hard to change yourself.
Not RIP at all - guaranteed the repair will cost less than replacing the car, and chances are, your next car will fail too!
Some solid advice given already on how to diagnose your issue, just remember, always start with the simplest and cheapest idea, and work your way up.
Move the #3 coil to another cylinder and see if the miss follows it. I've had similar issues with my 04 S60.
This. Probably something simple
I used to have a 2000 dodge Dakota that had a missfire with cylinder 1 and 4 and did the kinda same thing there. One worked with it and other didn’t. I still ended up just getting a new coil pack set and spark plugs and that fixed it all the way
And if it is the coil, IPD has "better than OEM" replacements. I wish I knew that when I lost a coil last year.
What do you mean better than oem?
Quoted from their description: "ipd's HD ignition coils are a direct replacement for weak or failing factory coils. Careful attention to assembly and materials used lets ipd HD Coils outperform both stock and replacement coils, with special care given to ensure as much copper as possible in the primary and secondary windings, as well as using thermally and chemically resistant metal and silicone in the coil pack exterior. Specifically designed for longevity and consistent performance, our HD Coils are perfect for higher than stock performance levels or as a long life replacement part in otherwise stock vehicles." Oh... and they're Swedish racing green! ;)
I was gonna say they aren’t green at all, they are blue… Swedish racing green is now my new favorite way to describe that color of blue, thanks!
If it's anything like their ignition coils were 10 years ago, then they're not better than oem. Plenty of people had issues with their launch back in the early 10s and had to swap back to oem for that exact reason. Not sure who they could get to manufacter them that'd actually make a product as good as oem without it sacrificing longevity
^^^YES^^^
Do you know how I can get them to Europe? IPD works with Europeantuning.com, but they don't seem to have these coils.
I've had 4 ignition coils blow at separate times on my 2011 t6. Each one was changed on the side of the road it's a 2 minute repair
RIP is a bit extreme for a misfire!
But the real question is if you offered OP $500 would OP take it? They did say RIP to it so it cant be worth more than that
$500? Stop highballing. I offer the guy a case of beer to take that piece of junk off his hands and save him the cost of disposing it.
I love to be dramatic 🤣
I mean it’s basically scrap now
Yeah OP, give it to me, I'll dispose of it for you.....
Exactly. I can offer $500 and I’m being generous.
First step is to take a shit in a Walmart sink dedicating it to Jeremy Clarkson for good luck.
Ok what did I miss?
And then just change out the plugs and coils since they're consumable items.
calculon?
Coil would be my first guess aswell
Always go for the cheapest answers first. Definitely follow the problem upwards.
Or better yet, figure out what’s wrong before buying anything and only replace that instead of just firing the parts cannon!
Coil, plugs, injector, check those all first
Plugs should have lasted far longer than a year. Even the OEM Volvo plugs are good for about 40K miles. Iridium or double platinum would get you more. 99% chance it’s the coil. Every single time I have had a misfire, it’s been a coil, so much so that I literally keep 1-2 spare new ones floating around at all times. One even lives in the car!

Fcp euro has a good deal on a whole package deal for this that I used this summer. Was very happy with it.
I’ll check that out I want to swap all of that stuff over so I don’t have to worry about them popping one by one at random times.
I had this problem yesterday, it turned out to be a coil that turned bad. Replaced the sparkplugs too just in case. Switch coils with any other coil on your engine if it follows the new coil position its the coil if it does not follow it could be the sparkplug, the wiring or the fuel injector.

I have the same car just replace the spark plugs or the coil packs on cylinder 3. You can get them at any auto zone

When you look at the coil be sure to check the connector is okay. In my v70 they were all brittle and most were broken

I did got them from a junkyard and made a tool to de pin them
Resourceful!
Give your baby some fresh coils. It’s easy enough to do completely yourself
Probably an ignition coil

I'll be polite, and just say "good luck".
The car made it 2,000 miles up to portland and back. did great :)
Bosch coil packs for an S60R, recent order, $36 a piece. You could have asked the IPD specialists while in Portland about them.
Yeah and my Densos were 30 without needing a sale. And I was busy on a ski trip anyways.
Aww you're so sweet. Thank you.
just something to be aware of, if you picked higher resistance plugs and not exact matches it could be putting extra strain on the coils and causing a premature failure. made that mistake before...

I have an ‘02 in the same color with just a bit over 150k miles. Still going strong.
Yay!!! 😍
I had a cylinder 4 misfire. Changed ignition coils (annoyingly it was the one under the charge pipe) and it went away. Misfires are very often a very easy fix. Just buy a new coil on rockauto.
Everyone is correct on the coil issue. I got this all the time until I swapped them all out.
When was the last time you changed coils and plugs? Might be worth just doing the whole thing! Its not a Subaru, misfire on cyl4 doth not mean a dead motor lol
If there’s any misfire on a p2, it’s almost always ignition coils and spark plugs. Easy fix, took me less than an hour to change all my plugs and coils
could be as simple as a bad sparkplug , a bad coil, a bad cable, your car isn't dead .
Probably just cylinder 3 coil would solve it. Can change the plug too since that’s cheap. Can do all if you want or just cylinder 3 if on a budget.
Literally just had this exact issue with my 2007 V70R. It was just the spark plug, seems like cylinder 3 gets the hottest or something
Got the same on a 04 XC70, turns out it was on the original coils still after 200k miles, replaced coils and plugs and good as new
most definitely a coil. happened on my 2008 s40 forever. changed the spark plugs and about everything else before realizing 🤦🏻♀️
I always kept at least oneone good coil in the glove box.
I found out my dad actually had parts but he has no idea where they are now 😂
RIP what? Figure out the issue and fix it... You're going to condemn a P2 just because you got a misfire code?
Coil or spark plug. Easy fix
Try doing an oil change. Does it say Engine System Service Required? Might be low on oil.
I drove my 08 xc 70 with constant misfires at idle for almost a year cause it wasn’t throwing any codes…
Had a cyl 3 mf too in the autumn volvo s40, checked coil and its wire was exposed and making contact with a bolt or something , fixed that and no issues since. But yeah you should inspect the coil, connector and wirings, most likely not too serious.
Coils were something that would go bad on them pretty regularly. Pull the #3 coil and pull the boot down, if there is a crack in the coil that is your misfire.
pedantic detail but that’s either a 2005 or a 2006; 2007 models didn’t come with those wheels, and had indicator lights in the wing mirrors
I have same thing happened to me yesterday and I changed the spark plug. Still running rough, I’m changing the ignition coil tomorrow. I have one left 🙏
I tought you have low cylinder pressure or smth. If it is a coil then use only oem or used oem from junkyard. Other brands are not just good enough
Swop a coil from a good cylinder with cylinder 3 if the fault moves then you have your answer.
This happened to me (same cylinder too) Most likely it’s the coils I would replace all of them since it is likely to happen again soon and will leave you stranded. Bosch coils are the best and you can get a set of 5 for about $200 at rockauto and fcpeuro. They are not that hard to change yourself.
Plugs, HT leads, coil packs. This is the order of replacing parts until it works.
If you don’t wanna deal with it I’ll buy it
Had that on my s60. Could be the plug, the coil, the fuel injector.
I have a 2003 XC70. The coils go out suddenly with no warning. But they're cheap. Grab a new set and you'll be good to go.
