Posted to European Driveability on 5/26/2005 22 Replies

this vehicle also had misfire codes, the other codes seem to have gone away, but the trim mal. codes seem to stay. customer replaced upstream ox. sensors with non-oem sensors, i'm wondering if this could be an issue for this codes.I don't have any vacuum leaks...
