strange smell

[305auto]

when i stop at a light, park and sometimes while i'm driving, i smell something. i'm not sure whether the smell is coming from the exhaust or engine. it's a sulfur smell. if anyone knows what it might be, and how to fix it, please let me know.

That smell comes from the catalytic converter alot. My dads cadillac used to smell like that all the time but my camaro never has.

it's got a brand new catalytic converter on it though. what else could it be?

Bad air fuel mixture, my friggen TB has that problem, but at 283 k its expected

check for exhaust leaks around your manifolds or EGR system...
