Sulfer Smell?

[BMW-ATI]

Im getting this like random sulfer smell coming from my exhaust,

ive heard this is from cat converters, but no clue

it's a 94 325is auto

98k miles?

Im guessing if it is cat converter, is there anything I can do to clean it out, that doesnt involve, like replacing it with a new one, I am low as heck on $$$

[Cruzin 323is]

u can try buying some cat cleaner, from a auto parts store..

i did.. and it actually improved my gas mileage!

What is a good brand? and how do you use it? and does it improve power any if my cat is really bad?

[Cruzin 323is]

i dunno what brand it was.. but i paid 8 bucks for a bottle!
u drop it into the gas tank!

bought it at auto barn!

sweet, do you think it'll improve power any?

The sulphur smell can be due to your AFM having some problem. Are you also having eratic idling speed. This are some of the sign that the AFM is jammed up.
You can service your AFM if you are the DIY type.

I have this similar problem before and I found that the vane of the AFM was struck in the fully opened position.

catalysts can't be re-energized to my knlowedge, but they can be cleaned. Apparently that's what that catalyc convert cleaner tries to do.

I would feel better buying a new cat than trying to nurse extra miles out of it. The world is polluted enough ya know?
