2004 GMC Sierra 1500 4WD T series missing- Changed plugs and light is still on but not missing. What else could it be?
No oil leaks on the floor. There was some oil on one of the plugs. Truck started to miss the other day and I changed the plugs but the check engine is still on. Any ideas on what else this could be?
Getting a P0304 code. So 4th cylinder misfire. I have no idea what could be wrong. One minute I was driving along and the next minute the truck is jerking and the check engine light is flashing. Anyone? Is this common?
