Default Having misfire need help
I have a 2012 1500 5.7

I'm throwing code P0302, which is a misfire in cylinder 2. My truck has a noticeable ticking louder than usual hemi tick. I have 98,400 miles on it. I swapped 2 of the coil packs to see if it was the coil and nothing. Next i changed the plugs and gapped them to .044-.045 and still nothing.

Anyone ever have this issue? Any suggestions on what to try next?

may have dropped a valve which can take out the cam. far as i know, the only way to be sure is to open up the engine and take a look.
