Hey I just got a brand new factory o2 sensor like 3 weeks ago. At the time my car was running UBER rich and i think it might have fangled the sensor a lil. I bought a universal o2 and tried it out, it worked a lil better but i think my stock one is fine, just needs some cleaning cause its covered in blackness.

Can I spray it down with carb cleaner and let it air dry then re-install it? I would like to just return this universal bosch crap and get my $80 back if its possible to just clean this factory o2 off.

I repeat, this factory o2 is like 3weeks old, so can i clean her up?

 

heat it gradually with a torch (too fast and you'll kill it) and turn it constantly (no hot spots)
no chemicals

 

do you think it could burn out in 3 weeks from running rich?

 

if it's real rich, it could def. soot it up enough not to work.. If it's running rich, then you've probably got a bigger issue to contend with..

 

nah well it was on a basemap at the time it was running super rich, thus the sooting

i think i will try just wiping it off and reinstlling, no chemicals

actually ill try slowly heating it with a lighter then wiping
