: Usually, the engine is either idling or just above idle, when something happens and the idle speed drops to about 500 rpm. Sometimes the engine tries to compensate and then starts to idle at 1500 rpm, other times, it just stalls.
: Afterwards, the engine cranks and I can get it to start but then as soon as I let go of the key, the engine is only idling at around 500 rpm and it just stalls again. I've noticed that it tends to do this more often when the engine is partially warmed up, but not fully at its normal operating temperature.
: Anyone have any ideas what it could be? Any help would be greatly appreciated.
sounds like you have a bad idle speed control motor(idle control valve) the computer controls the idle speed with this device and you may find its sticking.the computer tries to move it and nothing happens so it overcompensate's and sends a signal to move it even more the ,the motor then unsticks but its to low and engine dies.this is a common occurance.also check the throttle position switch to make sure the computer is getting the sigal to start controlling the idle speed(with the icv) at closed throttle.
