Misfire on 3
I'm having a misfire on 3 and don't know why. I've changed the plugs the connectors and checked the coils those are all good. I checked the injectors by disconnecting each and seeing if it had a affect on the misfire it actually made it worse as it should. I've heard people talk about spark knock and decarbing not sure if this is the step I should take, but any help would be nice.
Side note another problem I had was with the MAF sensor or probably not with the sensor. I connect the sensor I hear a sort of pumping sound I disconnect the sensor I hear it no more. What could that be as well?
Any help is much appreciated been workin on this for awhile and its driving me crazy!
