'03 Tahoe

[five0_4tluv]

previous to this morning i started experiencing erratic idling (down to 200rpm), after a repair shop drained my battery by mistake. the truck would idle really low (200-500), then to 1000 and back down, it even died on me at a stop light. problem went away after a few tanks of gas. someone told me it could be a battery problem. this morning i had a dead battery. battery was replaced and the problem is back. i had an injector cleaning at about 40k. what else should i be looking for? i've also had a few fuel filter changes, could it be the fuel pump?

My wifes Honda did the exact same thing after an injerctor cleaning.

 

Clean the throttle body.

That is what I did, and it cleared the problem right up.
