If I unplug the idle speed motor the engine will throttle right down and eventually stall. When I plug the idle speed motor back in it goes full blown back to 3,000 rpm. I agree this points to the idle motor and the ECU. The question I have, is there a sensor or wire that tells the ECU to adjust the idle speed located on top of the engine where Mike was working that could have been shorted or broken?

If it's back to normal, you need a new one. Coincidences happen.
