A couple days ago I had stage one injectors from full force diesel along with a terminator pump and new DP chip. I'm now having weird idle issues, idle fluctuates and jumps from 500-1000 RPM, sounds like its about to stall then comes back up. Unplugged ICP and seems to really help the problem, replaced ICP and same issue happening. Also, the #3 injector fluctuates between 3.3 and 5.0 on contribution test, all others are fine. Ryan at FFD suggested that perhaps the valve cover gasket is the issue since it is Dorman brand from NAPA. Anyone else have any ideas before I tear into this thing again this weekend?
