05 cavalier Random misfires cylinder 3
Thursday, April 26, 2018 6:41 PM
I have a 05 cavalier 2.2 I just started getting random misfires.the car will run perfectly at times. it will idle and I can rev to the limiter with no misfires. Then I move the car and it starts running horribly and stalling when watching my programmer I can see misfires on cylinder 3 mostly some on other cylinders. That keeps up for a little bit then will clear up and run fine intill I start to move it in my driveway and it happens again.

I have a good running car that I have changed coil pack plugs, tps, injectors,crank sensor, also have checked fuel pressure have 60 psi. Anyone have any ideas Iím running out of them quick donít know why this problem is so intermittent.

Spark plug gaps? Plug wires in good condition, not old brittle, cracked, cross firing, grounding out?
