ls1 missfire
my 2000 pontiac formula has missfires on several coils but only above idle. ive changed plugs wires and even swapped a buddies coils onto the car. and still same issuse. My question is what else could it be pcm, ground, harness, maybe the tuning in the computer has went to crap idk?
any suggestion?
