Idle Learn Procedure

WARNING: This page is about a different car, the 2001 Cadillac Seville, 2001 Cadillac Eldorado, and 2001 Cadillac DeVille. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: When Powertrain Control Module (PCM) or battery are 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 and allow it to idle for 15 seconds. Turn ignition off. Wait 15 seconds. Restart engine and check for proper idle operation.
