    Anybody know what if any "special" tool is needed for replacing O2 Sensors?
    After replacing my coils I again after about an Hour on the road experienced bank 1-4 slowdown light and obvious shut down of Rt Bank.
    Interestingly I unplugged my Coil on Rt Side and wiggled O2 sensor wire and when I started it up was no longer showing warning and running smooth Gonna replace O2 sensor next (Both)

    Removed air filter and able to get to plugs for O2 sensors but impossible to get to sensor it’s self. Need to take off rear wheel?

    There is a standard tool that lets you remove the sensors, probably possible without the tool - but harder I think. I don't remember the O2 Sensors being particularly hard to reach, but that's assuming you have a lift. All bets are off if you're using a traditional jack.

    These are connected to the Cats, right? Why would you need to remove the wheel?

    No lift and can’t get car high enough to get fitting around nut on cat.
