Inconsistent idle and stall.

Ratpatator · Dec 15, 2016

Just got home from work and letting the truck idle in the parking lot it started idling funny up and down and then died. Started back up fine but still idled up and down. It seemed to have a little less power on the drive home I just assumed it was the head wind I was driving into. Do our 6.2 motors have an intake air control valve or something similar that could be going bad ? No codes were thrown that the sct tuner would read anyways

Try cleaning the mass air flow sensor. Especially if you have been anywhere dusty or cleaned and oiled you air filter recently. Good luck.

Update on this. It turned out to be a burnt spark plug wire on the pass side on the back last cylinder for anyone with the same issue.

Inconsistent idle and stall.
