2004 GMC Sierra 1500 4WD T series missing- Changed plugs and light is still on but not missing. What else could it be?

Asked by Jul 12, 2015 at 10:19 PM about the 2004 GMC Sierra 1500 4 Dr SLE 4WD Crew Cab SB

Question type: Maintenance & Repair

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?

1 Answer

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?
