The vehicle is running real rough after the spark plugs, coils, & mass air flow sensor was replaced. The fuel pressure is fine. What could be the issue? There were no CAT codes, just missfire codes that are taken care of now. The vehicle would not start & had the missfire codes initially. It just runs real rough now, not to the point of dying, but rough.
have the same problem?
