2003 Cadillac CTS 3.2L Poor Idle Quality, MIL Lamp on
Posted to GM Driveability on 9/14/2010 7 Replies

Hello fellow Tech's, I have P0221 Throttle position sensor condition. This is an intermittent condition only happened once before. Flow chart lead me to intermittent Diag. and I found nothing. TSB shows very little help. Thanks for ANY help.
