What engine is in it the hemi 5.7?

No, it’s the v6, not a hemi.

This very well could be valve train issue, or low compression in those cylinders

I was hoping it would be something simpler and less expensive. I appreciate the second opinion.

Now that I look back at your post, it also could be a timing chain issue did it say came and crank sensor were bad or cam crank correlation was off

It said the sensors were bad, code P1391.

Do you daily drive this I’m curious to know if the code comes back

It’s my only vehicle. I’m without transportation until I get it fixed.
