do these 02's look shot?
 

i think they are just about dead lol.:mad:
got a p0155 02 ses code and i think its safe to say its the 02's.
wierd thing is that i put my headers on about a year or so ago and they dident look so bad.
when my car was tuned the exhaust smelled clean going from it being untued for the headers and running rich then i noticed the last few months the exhaust got more gas smelling so maybe it was just the 02's on there way out.

dont think you can go by looks......if you get a code.....toss em

Mine are pure black and I tried spraying them with maf cleaner and rubbing with a cloth and they are still black as coal. My exhaust also smells like the car is running richer with a gassy smell and fuel economy seems lower than what other people have on here. Looks like we both need some new O2's haha.

well they werent that black when i put them in the new headers and io dont think trying to clean them will help.
time to go to the parts store.
