Alright guys, I replaced my driver side o2 sensor about a month ago. Now, I am getting more codes again, for the same one. They are P0133, P0134, & P0135. My car has been dyno tuned and it seems to be running fine otherwise. The codes aren't tripping a SES light because the PCM has been tuned for the longtubes and dumped mufflers off of the collectors, but when I scan it using my Aeroforce guage, they show up. (They must be set up as "No SES Light") My question is, would it be okay to race it tonight or will my A:F be all screwed up and will I not be at full power? Let me know, thanks!

when you got WOT, you are in Open Loop, so the )2's arent even used....
and if your PE is set right, Itll put you at a sarfe AFR anyways.

Which codes are they exactly?

Well, the car ran great last night. Stronger than it ever has before. I reset the codes and drove 80 miles to the track. I let the car cool down, made a pass, and still no codes. I am going to monitor them and swap out the Bosch o2s for the Denso ones.
