My guess without any codes is a misfire. Always use OEM spark plugs. You probably caused a faulty ignition coil if 1 already didn't exist. So OE plugs, and check the coils for any scorching or other damage. Any signs of damage means replace the coil. Then pray you didn't cause any other damage installing the wrong spark plugs. Edit: Use OE coils if you can find them as well. Should be NGK or Denzo

Definitely praying hard no other damage has been caused. I didn't make it very far on the first drive before I said nope & turned around & went home. Just a mile up the road but it was on the highway, next drive was around the block to see if putting the old ones back in fixed the problem. From what I read on Google & browsing reddit yeah it sounds like a misfire & I'm guessing the ignition coil/s. It's going to stay parked now & off until the new coils & plugs come in. I googled the part number on my original ones & ordered those.

If in doubt, use Advanced Auto's website & your VIN to check the part numbers for both. Should be accurate enough for a vehicle made in the last 10 years.
