    first, if you are going to diy pick up a $ 20 chilton or haynes manual. secondly the o2 sensor is located on the exhaust manifold at the front of the engine under the metal heat shield. easy replacement job.

    It's before. I'm really curious though.....at what point did your Corolla become a Cadillac? Where can I get a converter like that?
