    smell?

    Hello everyone!
    So, im just curious if anyone else has experienced this issue. My car wreaks. i cant exactly tell what the smell is, but its when the car is running, typically warmed up. My exhaust smells like raw fuel a little bit, but the rest of the car smells like...sulfur? Idk. i cant exactly describe the smell, but its distinct. It was a lot worst when running on supreme(93) versus regular grade. I did install a new catalytic converter (which was, from what i was told, is the cause of this smell) buts its well past that point. Its been on the car for about 2k miles. The car isn't tuned, only a cat-back exhaust. Anyone have any ideas or at-least shares the same problem?

    Could be way too rich and overheating the cat?

        When did you last change your air filter and o2 sensor?

          air filter about 2 months ago. Its clean anyways, plus an intake is in the process of being fabbed now. Also, i had to change the front o2 sensor also about 2 months ago after i threw a CEL for it.

            Oh right OBDII.........

            Bad FPR or clogged return line? I don't really know what to tell you, I'm a first gen guy. It does sound like you're running too rich.

            Take your cat off and see if the smell goes away.
