Misfire and issues running
I am having trouble getting my vehicle to drive again. Its a 2015 caprice with a dod delete, cam, and a tune. It started misfiring one day. Several rocker arms had come loose, so I put some teflon tape around the threads and blue loctite under the head of the bolt and torqued them all down properly. I thought might have been the issue, but no the vehicle was still misfiring with a p0352 code, so I figured I might as well change the coil packs and spark plugs since it was about that time, start it up and still misfiring. I figured the gas maybe, so I drained the tank and put fresh 93 in, but still no. I have checked the compression, and I have done a leak down test which both were good. I am just confused right now and cant think of anything else. Ive swapped injectors, and the issue never followed. The vehicle is getting good fuel pressure. I am not a mechanic by any means, so any help or advice would be greatly appreciated. So far the vehicle will start up fine cold, but if I shut it off then try to start it again, it wont fire up.

Sorry for the late reply. Have you checked that there is an actual spark at the wire? Power and trigger at the coil connector? That code says that there's a problem with the circuit to that coil so that should be your focus.
