    My new headers & problems

    I put on RD headers and the car runs like shit like a have a VAC leak. It stutters at the start and runs rough. I unpluged my o2 senser and it runs fine. Do I need a new one?

    sounds like O2, ie, if you remove a part and the car acts better chances are the sensor is bad, or atleast thats what i have found

      Ya, sounds like the o2 can not read correctly anymore.

        Try unplugging your battery for a while so the OBC computer resets. I have heard that this will allow the Motronic system to reset and readjust itself.

          or maybe he touched/got grease on his old O2 sensor (which was on it's way out) and caused it to go bad prematurely.

            I'm no expert, but it sounds like it could have to do w/O2 sensors.
