P0301 Chevrolet - Taction Control and stabilatrack turn off becuse of the missfire

Question

My Chevy Avalanche is not burring the spark plug on cylinder one it comes out wet still.

Answer 1

Hi there,

I would start with replacing the ignition coil for cylinder #1 and the plug wire. Either of these failing could cause the misfire and if it's failed will prevent spark on that cylinder. As a test you could try swapping it with the one next to it and see if the misfire moves with it. If it does, then you know the coil is no good. If not, then you may have a wiring problem or an issue with the fuel injector.
