I have had my 2003 350z throw up a P1273 code (Air/Fuel Ratio Sensor 1) twice in the past couple of weeks. The car drives fine and I can reset the code, but can any one tell me what I need to do or fix to stop the error code from being reported?
BTW - I have Berks HFCs, plenum spacer, a cold air induction kit and my car has been uprev'd several months ago.
