Updated this is for Bob & Ken you said to remove the idle air control valve in my repair manual it is called a idle speed control valve (isc)
i hope this is the same thing I did remove it from the vehicle and cleaned it I also tested the throttle position sensor and airflow meter which are in repair manual specs what next
have the same problem?
