Hi,
My buddy has a 92 chevy pickup, and when he pulls up to a stop light after the engine is at operation temps, the idle will drop really low, and the truck shudders like it want to die, but then jumps back up again. It only does it at idle speed. It is a 5 speed with the 350. We have cleaned the IAC, new plugs cap rotor wires etc. but still no luck. Does anyone have any ideas? Ya I know, its a chevy and thats probably it
