I went to the track today and noticed my car was not running very good. I used the autotap and made a run. My O2 sensor on the driver's side read .88-.89 all the way down the track. My passenger side O2 sensor was .44-.45 down the track, at idle, at part throttle, well all the time. I never did get a SES light so do I need to replace it or what.

Been there, done that. That O2 sensor is likely toast. Make sure that no wires are cut and that the connections are good. If you find nothing wrong you can try cleaning it up real well but if that dooesn't work it's time for a new one.

BTW, you'll get an SES light eventually. It just takes a few driving cycles.

 

Thanks Colonel. I went and ordered a new O2 sensor. I will check the wires when I change it out.
