Hey guys Im in a bind at the moment, My car ran rich for few hrs when I got tuning done so now my bank 1 O2 sensor is BLACK as night but the actual sensor its self is ok (just the outer layer is black) I need to clean it i read a few places that I can use CRC Maf cleaner. What do you guys think?

Regards michael

Mod you can delete this i found out you can use CRC MAF CLEANER but its 50/50 chance it will make a difference. Also be careful not to get any grease or oil etc on the o2 sensor its self.

OK just finished. Worked Great, My A/F are reading normal now.
