Does anybody have a bidirectional scan tool to actuate the idle air control? You can see the response if the stepper motor is opening or closing. At least have a logic probe to test for power at the harness connector. The stepper motor has light/blue and green/black wire which alternately change polarity. The other four wires are confirmation wires to feedback to the PCM if the desired position has been reached
