What would cause this, an exhaust leak?? Not a very powerful smell but a subtle odor that I smell particularly when I'm warming the car up. My cat is only a couple months old so that shouldn't be a probelm.

Actually, i think that the smell is coming from your cat...new cats usually have a smell to them...thats how mine was..

ya it did that after I first installed the cat (for about a week) but that was 4 or 5 months ago.

Your cat could theorhetically have gone bad again, if you're running really rich.

Naw, coolant is a sickly sweet smell - I remember from when I had the typical radiator leak.

Ok, so "could" an exhaust leak smell like that or would it have to be the cat? Now that I think about it I guess I don't know what exhaust fumes smell like before they go through a cat *shrug*

Ryan - is there an easy way to tell if I am running rich?? If I was running rich what is the typical problem - bad O2 sensor? fpr?

^ Um, not that I can think of.

A bad 02 sensor could cause a rich condition. I'm sure there's others here who are more knowledgeable than I.

ya new cats need to be broken in... so they'll stink at first

hmm, mine has never smelled like sulfer, and without a cat it still dont smell like sulfer. When your running rich it will smell like gas, really simple.

What i was saying, when you have a small coolant leak, and it burns off it smells different. I know its usually a sweet smell.

Coolant has a sweet smell, but sulfur smells like fart or as some have reported "rotten eggs"...thats just the smell of the breaking in of the cat...ride with it for a month and see if it still smells...

Haha, this is funny! It's not a "new" cat!!! I said it's several months old now and yes it smelt bad originally but that smell went away a long time ago!!! Now a different smell is there.

omg, lol, before I let poor subx repeat himself for the third time, he's not suggesting a coolant leak, but coolant being burned (for instance, if you had a bad head gasket).
