Thank you for the response. I have already removed and cleaned the throttle body and all the ports and chambers. I replaced the IACM, tested the throttle position sensor, temperature sensor, coil pack, fuel filter, PCV valve, EGR valve, O2 sensor, plug wires and spark plugs. I changed any suspect vacuum hoses. How can I check to see, how low the RPM's are dropping? What should the idle RPM's be? Thank you.
