Juppalgae,

Did you get anymore hits on this? As need to change my O2 sensor as well. It is the front right side tht needs to be replace but I'm thinking replace both of the front O2 sensor. My car is close to 120K miles. The front 02 sensor is relatively cheap. Changing the O2 sensor shouldn't be that difficult. I'm surprise that no one have a write up for this. Any help on this would be greatly appreciated.
