1996 Pont. Grandprix, 3.1,100000miles.P0172 system to rich bank 1. I am unable to get rid of this code.I have done a complete tune up, plus these new parts and sensors converter, o2sensors, mass air flow, map, throttlepos. Idle air control, egr, gas cap. Also fuel press. Is good. The car runs great but will not pass inspection if I just keep erasing the code. What else could this be?
