I am having trouble with my 2003 Chevrolet Silverado 1500 LS. Its idling very low RPM, about 500 rpm, and stalling. Causing battery gauge to go down.


Depending on which engine you have, there should be an idle speed control motor or air valve that controls idle speed.
It could be faulty or dirty.

The idle air control valve is what regulates incoming air when the engine is idling. In some cases these can malfunction and cause intermittent issues with stalling at idel until the IAC dies altogether.

1992 LEXUS LS400 STALLS WHEN HOT & IDLE SURGING


Had same problem on 93 LS400, timing was off one tooth on left camshaft gear. Replaced belt and reset and no more problems. (Spent 1200.00 on repairs I did'nt need)

Rough idle


I took mine in to change the plugs and they said there are four O2 sensors in the fuel mixture system and two were bad. I didn't replace them since they were a little pricey ($500 to replace both) and I have 103,000 on the car. Has very similar roughness and occasional oscillations, but no stalling. Hope this helps.
