Question for All you familiar with the 7.4 engine. Truck turns over for a second or two then starts. After about 7-8 seconds idle will dip down close to dying then come back up and repeat. Wile driving every thing seems good and smooth, engine doesn’t spit, sputter, stutter or hesitate when giving it throttle or cruising. Also no dash lights, dosnt have any strange smells sound coming from it, and no puff of smoke when starting or driving. Possible fuel supply problem? Also been hearing could be a bad ground?
