THIS IS MY PROBLEM...WHILE IN IDLE EATHER PARKED OR ON GEAR. THE RMP FLUCTUATES DROPPING SLOWLY THUS SHUTTING OFF TRUCK. I CAN AVOID THIS PROBLEM IF I SLIGHTLY STEP ON THE GAS OF COURSE, BUT....ANY IDEAS? I CANT SEEM TO FIND THE PROBLEM. my truck pukes so to speak then it diesi think it is the Carburetour because i know it is running too rich HELP!!!
It sounds like a vacuum leak. Check all your intake bolts for tightness. Dump some hot soapy water along the gaskets with the engine running. . It should bubble like crazy if it's leaking. Check all hoses for cracks and tightness. Use a stethoscope or a length of fuel hose held to your ear, and witht the engine running, wiggle all hoses around while listening for a hissing sound. Make sure your choke plate is opening all the way. Check the vacuum hose to your modulater valve on the tranny. Check the bolts at the base of your carburator, and the base gasket. Check the timing. Hope this helps.
