    Go to the autoparts store and in their Help! section you will find sparkplug anti-fouler part #42002. You will need 2 of them, a 1/2" drill bit, and some exhaust thread anti-seize paste. Take 1 anti-fouler, put it in a vise, and drill it out with the 1/2" drill bit. Take the second anti-fouler add the anti-seize paste to the threads. Now you take the one you just drilled out and screw it into the second (non-drilled) anti-fouler. Using your calibrated elbow, turn a 1/4 past handtight. Remove your Bank1Sensor2 (O2) from the s-pipe and unplug from the car. Carefully coat the threads of the O2 sensor with the paste.
    :eek: ***Do not get any anti-seize on the tip of the sensor or the outside casing as this an damage it and/or make it read incorrectly****:eek:
    Remove assembly from the vise, coat the second anti-fouler threads with the anti-seize paste, and install into the vehicle. Use the same torque settings, plug up the sensor to the harness, and reset you ECM. In 20-50 miles your ECM should recalibrate the sensors. At that time you will see a DTC code for Bank1Sensor2 or you will not. If the latter is the case, then you are set.
