I've heard this before, that the engine should die if you unplug the idle speed motor connector but I still don't understand why. (Mine doesn't die.) As far as I knew the idle speed motor will stay in what ever position it was when it is unplugged. Is this not the case? If I unplug mine when the engine is idling slow it stays slow. If I unplug it when the engine is idling fast, it stays fast. I am not aware of any mechanism within the idle speed motor that closes off its passage way when power is removed. Who else can shed more light on this?

The motor should stall when you pull the plug on the idle motor. Check that the brass screws are closed. Check the throttle plate adjustments that the throttle plates are closed all the way.
