Ok so thank you in advance. I have a 2003 wagon. Just had the head gasket replaced. Ran better then ever for 2 days now I have a cel for missfire cylinder 1 an my exhaust smells like straight gas with white smoke....I put new pugs in before I took it in to get a head gasket cause it was throwing the same code. Is is cylinder 1 coil pack would that make it run to rich an smell like gas but why white smoke? Cars still idles an runs great just a very minor miss. I cleaned my maf. Do I need to do a hard reset? Any help please
I have that's why I cleaned my maf. The smoke an smell I haven't been able to find out if that's normal for a bad coil pack or should I look else ware injectors an such.
May have a botched head gasket install there. White smoke is often an indicator that coolant is getting into the combustion chamber. Check your fluid levels and see if coolant is dropping. If so, suspect the head gasket is bad again, likely due to poor installation.
If a coil is bad and the cylinder is not firing, the gas will just move out with the unspent air into the exhaust system, so that could easily be a culprit as well. Move that coil to another cylinder and see if the misfire code follows it, if so the coil is bad.
