RE: How to change o2 sensor
Step 1: Unplug the greay 4-wire connector on the transmission housing running the the O2 sensor in the exhaust manifold.
Step 2: Saturate the O2 sensor with penetrating oil/WD-40/ or the like. Don't do this if you plan on reusing the sensor, I don't know if that will foul it.
Step 3: Using a oxygen sensor socket or the correctly sized wrench, remove the sensor.
Step 4: Replace sensor with a new sensor. Not sure if you can apply anti-seize compound on the threads.
Step 5: Watch your gas mileage over the next few tanks to make sure it's within normal range to make sure the sensor is functioning properly. Also, make sure the CheckEngineLight doesn't come on.
