Idle Learn Procedure

NOTE: When Powertrain Control Module (PCM) or battery is disconnected, PCM loses power, or PCM is reprogrammed, PCM learned idle position is lost. When learned idle position is lost, engine idle will be unstable.

Start engine and allow it to idle for 15 seconds. Turn ignition off. Wait 15 seconds. Restart engine and check for proper idle operation.
