Fouled O2 Sensors

[Chuck Venit]

Is there anything that can be run thru the enginr to clean fouled O2 sensors? or am I stuck replacing them?

Depend on how fouled? If it's just a bit carboned up you can try heating them with a torch CAREFULLY and then hitting them with a cleaner.

No good deed goes unpunished , had to replace the 2 ahead of the cats.
