HiCustomer

 

 

 

Thank you for asking your question on JustAnswer. The most common cause of the problem you are having is a defective IAC (Idle Air Control) valve located on the throttle body of the upper intake manifold (see diagram below), I am also sending you test procedures. I hope this helps you out.

1. Keep the engine running by giving it just enough throttle to keep it from stalling.

2. With the Idle Air Control (IAC) valve connected, monitor the voltage across the 2 wires at the IAC valve connector. The higher the voltage, the harder the Powertrain Control Module (PCM) is trying to raise the idle. Expect more than 4 volts if the idle is lower than normal.

3. Then, with the engine running at a low idle speed, unplug the connector, and if the RPM does not drop when the connector is unplugged, replace the IAC valve.
