Answer
Are you referring to the ISC (Idle speed Control) motor on the opposite side of the throttle body from the TPS ?.


I can provide you with some pictures and diagnostic procedures to help you test these circuits.

What has probably happened is that you lost your 5 volt reference signal from the ECM. the information that I can provide you with will verify this.

If you can read electrical schematics and follow diagnostic procedures and use a digital volt/ohm metr I have the information and the expertsie to get your vehicle running.
