Ensure Idle Air Control Valve (IACV) and overrun fuel cutoff operate with the throttle closed. Check throttle position sensor. Check voltage at mass airflow sensor pin No. 1 or 2 (zero volts) and pin No. 5 (12 volts). Check mass airflow sensor output voltage. For adjustment procedures, see ADJUSTMENTS article. Repair or replace as necessary.
