Sometimes it drives ok but most of the time it acts up. We will be driving and the RPMs will fluctuate, car starts jerking, and sometimes it dies. We tryed putting heet and berryman b-12 in with a full tank of gas but it didnt stop the problem. He usually runs on a low tank of gas so that might have caused the problem?
