![Question](https://mbworld.org/forums/images/icons/icon5.gif)
Hello just had autozone run an obd scan and found that I have a bad o2 sensor. I am going to replace it soon as the part comes in, but my question is should I replace all 4 of them at the same time? or would the other 3 be ok for a while?
also saw a youtube vid that cleaning the o2 sensors instead of replacing, valid option or no?
any advance would be awesome thanks!
