Cylinder 2 Misfire Nightmare!!!
Hello every one, i will start off by saying that my car was running great, and when i parked it and went to start it the next day i was stuck with a misfire in cylinder 2, pulled all coils while running and only coil that showed no change was cylinder 2, i have a new set of coils and ngk plugs i threw on and also replaced the ignition coil harness as the wires where cracking and there is no change, so i swapped all the injectors thinking that might be the problem and apparently it was not, my next step was a compression test which revealed 180psi across the board, and a leak down test which passed also.
i dont know where to look next, i then thought maybe it was an ecu issue as i have a ECA Concepts tune but i threw in my stock ecu and also a ecu from Reflect Tuning and my stock ecu with no change, checked the o2 sensor and its working fine. i will include a video
I'm not loosing coolant
and compression was
Cylinder 1 = 180psi
Cylinder 2 = 180psi
Cylinder 3 = 175psi
Cylinder 4 = 180psi
and i also checked the timing and it is spot on.
Im stumped and cant keep forking out out gas for my Silverado...
