2003 Cadillac CTS 3.2L Surge, MIL Lamp on, Extremely High Idle
Posted to GM Driveability on 3/19/2015 5 Replies

Vehicle was brought in with an extremely high idle that was surging at times ([...] RPM) when in park. Cleared the codes from both the engine and trans modules. After about ten maybe 15 minutes the idle settled down to a normal level and was no longer surging....
