O2 sensor
I have an O2 sensor code of low voltage and slow response. Is this critical? I tried to remove it and it won't budge. I tried to heat it & still doesn't move. I was told if I could get it out to heat the tip to clean it. Is that true? Thanks

Well, your O2 sensor is definately shot and needs to be replaced. The heat method is best. Sometimes the sensor is too stuck or will strip the threads off with it. In a worst case, you can cut a new hole next to the old one and weld a new beshing in. Make sure that you do not use a ss bushing, and that you use anti-sieze with the new one. To help ensure the best performance, replace the sensors every 80K at most. I would replace the other sensors at the same time.
