STalling ,Erattic idle speed, Cleaned Throttle Body,Ok now
Stalls out at low speeds.
engine skip when idle on D
Being worked on right now. ruff idle , close to stalling.
Low idling when the engine is warm, almost stalls at a light. How to get it fixed;
Avalanche would start normally and run at low idle speed while engine was cold. After the engine warmed up, it would stall every time I took my foot off the accelerator. My mechanic, Gene, cleaned the throttle body and it's been running fine so far (two days, 50+ miles).
