Hey everyone.....i have a 95 gs with an iceman CAI, greddy header and downpipe, with a mozart racing exhaust. Lateley I have noticed that my car smells like the 02 sensor is bad...i asked my stepdad what he thought becuase he is a mechanic at a dealership, and he also thought it was my 02 sensor. I am not getting a cel code though?? what do you guys think it could be???

My CEL has been going on and off for a little while due to my O2 sensor...maybe yours is going bad but just not registering for the CEL to come on?

Your Ecu will not notice a bad O2 sensor for ever... You would have to drive on the highway for like half and hour, on cruise for the computer to eventually notice, and throw a CEL.

But if you are burning through a lot of gas, and are puffing some black smoke that could definatly be your problem.

could possibly be a cat going bad too.

if your O2 sensor was bad your car would run like shit.... that is if its the upside o2. if it was the down side eh. I have never heard of a O2 sensor smelling bad.

usually if you're getting a rotten egg smell, it's your cat - your o2 sensor is probably fine unless you're getting terrible gas mileage
