1996 Chevrolet Monte Carlo Z34 3.4L MIL Lamp on
Posted to GM Driveability on 5/15/2004 17 Replies

complaint by customer CHECK ENGINE LIGHT ON found code P0172 system rich & LTFT @ -20% / STFT 8 runs like a 3.1L instead of a 3.4L (a little weak)

please see history and specs @ bottom of page...I would like to add that the vacuum gauge wandered 1/2 inch back...
