Ive been having a small problem with my car from time to time, the exhaust smells like rotten eggs from time to time, has anyone else had this problem? Any help on what it could be?

 

Fouled catalytic converters?

 

What brand of fuel do you use. If Shell, they have problems with this. That is actually a Sulfur smell and if you use it, you may notice this from time to time. I know the Mazda6 has had this problem, yes they had Cat problems, but Shell was the other problem. Chris

 

Not Only That It Also Comes From Not Giving Your Wot From Time To Time. Not Doing So Builds Up A Bunch Of Crap In The Piping And The Cat. So Stepping On It Flushes It Out

 

You know it might be because im not going WOT alot - I have a bad clutch and stay away from WOT due to the fact it will slip , As for the GAS I use BP (Ammoco) 93 oct. Im also suspecting I may have a very Small exhaust leak (the other day when it was warm I could hear a small ticking sound comming from the exhaust when I got on it a little bit and had a wall to reflect the sound back to me. Its only done that like two times and Its been on warm days.

 

If it's a leak before the cat, that may be your answer.
