    bank one o2 is the one in the rear manifold, bank 2 is post cat.

    post the code, if it could be a vac leak, not a o2.

    if it is the o2, you need a o2 socket to remove it.

    ANNNNNNNNNTTTTTT

    3800's only have one bank because the exhaust is combined into one pipe before the first sensor.

    Bank 1 sensor 1 is in the rear manifold
    Bank 1 sensor 2 is after the catalytic converter
    I drink..so consider that when reading my posts.

    Well, I think I lucked out then since I was not looking forward to getting to the rear manifold.

    When I go to pick up the O2 sensor, I will scan it again and get the code.
