did you check your maf? could be an ignition problem if it kicks in at high rpm check codes.

take it apart, the 2 screws on top. be VERY careful when you do this, youll see 2 tiny strips of metal make sure they are intact .

clean it with some Q-tips, and there cant be a SPEC of dirt or carbon! then rest the ECU and try that, it fixed mine! if that don't work then try some new o2's
