I have a 2001 z24 with a misfire #1. i changed the plugs,boots, and both coils. still has rough idle. what should i replace next?
dont just replace parts now ur out the money u payed out for those parts check cyl one injector ohm it out and check compression thats the last things u have to check
Thanks Tom. Got it figured out now. It was the coil housing. I was told those seem to go out regularly.
