Having a diagnosis issue hoping the community can help hone it in:
2011 Coyote w FRPP Supercharger (M-6066-MGT624), JLT CAI, catch cans, Kenne belle boost a pump.
Symptoms:
Rough Idle, Stalling w Clutch In on deceleration, exhaust overrun pops&bangs sound weaker and more irregular than the singular strong pops at first, sluggish throttle response. No Check Engine Light and Dyno did not reveal any issues.
I have datalogging from SCT X3 and LiveLink. Compared some signals from now to some runs I did months ago when she ran fine. Knock Sensor seems more erratic, going negative more often for longer.
I'm thinking IAC or EGR/bypass valve. Is this something that can be easily diagnosed / checked / maintained?
Thanks in advance!
