Question about 2007 GMC Sierra 3500HD

1 Answer

Sierra 3500HD rough idle

80,000 miles. Just have the trans rebuilt. Had new fuel pump and sending unit put in about two months ago. Problem now is the following: Had truck back one week from trans rebuild. Ran fine until today. Truck will idle a little rough. When driving it will just bog down when accelrator is push down. When you let off will run but at a very low speed. Trans is automatic and does this in all gears. Don't believe this has anything to do with trans. Could it need tune up or some sensor?

89 Wagoneer drives rough


The thing to do now is a fuel pressure test pump could be weak just a few pounds under the recamended pressure will do that weather its mechanical or electrical . Is there a filter in the carb. wear fuel fine hooks? If none of this is an issue at least you can eliminate fuel deliverly as the problem.

Rough idle


check you throttle position sensor first then fuel pressure regulator, then fuel pump. i have a 92 and had to recently do a massive overhaul. my rough idle was caused by a malfunctioning tps with a small exaust leak causing it to race and an intake manifold gasket. also check your idle speed adjustment settings.
