OK I HAVE A CHEVY SILVERADO 1500 WITH A 4.8. IT HAS AN IDLING PROBLEM.

2000 Chevrolet Truck • 196,000 miles

Somedays it idles and runs perfectly, and some days it does not. It does it mostly when the engine is warm. When I first start it in the morning it usually runs great. It if fails to idle, it will stay running if I hold the throttle down a little bit. Also, if I turn the key on and off a couple of times, then start it, it will keep an idle. I was just wondering if you could tell me some possibilities of what could be wrong. Any help would be appreciated. Thank you.

Clean the idle air control valve and see what happens
