[QUOTE="fordfreak4life, post: 1526690, member: 212"] This is going to be a long story but I'm hoping someone can give me some fresh ideas. My dad did some work on his pickup and for some reason had the engine harness unplugged from the uvch and got a piece of the foil off the hvac box in the connector before he put it back together. The pickup started but of course having a direct short in that side it was only running on 5-6 cylinders. I found the foil that caused the issue and removed it. Started it back up, same issue. I put in new uvch and wiring. Issue remained, so I replaced the idm. Issue remained, I then ohmed out the harness from the IDM to the injectors and it ohmed out fine. Swapped the injectors that were showing misfire and the problem stays with that cylinder. Compression tested the cylinder 365psi. Replaced the pcm, and the issue remained. Anyone have any other ideas to try here. I'm pretty well stumped [/QUOTE]
