mpg9999 09-03-2002, 12:39 AM My ECU is giving me the code for a bad o2 sensor. It's only a few thousand miles old, and I have no issues with poor gas mileage. Last tank of gas I got about 31 mpg. Anyone got any ideas? TIA. And oh yeah, 500th post, woohoo! Probedude 09-03-2002, 10:03 AM What year? Originally posted by mpg9999 My ECU is giving me the code for a bad o2 sensor.
