2004 Pontiac Montana 3.4L Surge
Posted to GM Driveability on 3/12/2010 11 Replies

This vehicle surges under acceleration. There are no codes, and no misfires listed on the monitors. It acts like a MAF sensor, however, when we disconnected it, there was no change. I did see some slight fluctuation in the TPS readings, but there was no change...
