not yet i wanted to see if someone fixed it.

when i cleared the code and did a freeway pull 100-80 coasting in neutral all the dash lights come on, put it back in gear and they turn off.

im sure if you take it to a tuner they can remove that from the ECU...then you can blow your engine if you want

well as long as the car is running smooth then I would get it tuned. Once you get it tuned the tuner should disable the rear O2 sensor so that code will not continue to appear

Question:
Do you get a check engine light + flashing cruise control light? Does this happen on cold days or all the time in 4th at WOT?

Usually that will throw a CEL + Flashing Cruise. Pull the code and it will read something along the lines of a wastegate malfunction.
