    Default O2 Sensor Cleaning?

    I have heard that you can clean O2 sensors, has anyone tried it with success? Did you use gas or another method?

    I heard guys trying everything from gas,MAF cleaner, throttlebody cleaner none having any good results. If you have a bad O2 can't hurt to try.

    I would just change or try to clean the front o2's, there the ones that control the engine. The rears are for emissions.
