I just pulled in to work today and noticed a nasty rotten egg smell. Thought it was the air and nothing else. Then later I pulled it into the garage (I work at a stereo shop) and then my boss said "wtf is that smell" and I was realized, crap, its my car that smells like it just farted....

I did a few searches, and the two potential issues are the battery and the cats? My car hasn't set a CEL or the "Check gages" light yet. On the gauge cluster battery voltage reads around 13.5v.

What should I look out for? Should I test for anything? Sure'd be nice to have a new catback and high flow cats, but it'd be even better if that wasn't the problem.

 

Maybe there really IS a rotten egg in there?? Check under the seats!

 

That's what you get for picking up nasty bitches..

 

the cats can give off that smell, but usually only when they are new.... you could do a fast highway rin to heat them thru...

but my bet is that someone stinkbombed your car.... anyone have a motive??, or do you live next to a 13 year old who hates you??? (buturic acid smells like rotten eggs)

 

Damn Rotton Eggs....................

 

its just your cats

 

I doubt someone messed with you car I agree with this guy

 

ya its just your cats

 

X2, it's gonna be ur cat converters that are going out. Had that same prob on both my 93 and 98

 

a battery being overcharged also has that same smell. i had a battery blow up in my 68 chevelle when i had it. of course that is a totally diff charging system. it had an external regulator which went bad, now there all one unit. still could be going bad. i would have that checked also

 

I think that could be the battery.

 

my made the same smell. This happened when i ran it for awhile. Then it went away. I dont think your cats are going not. just the nature of the beast

 

It is for sure your cats.. Or you have someone who hates you and puck rotten eggs in your glove compartment!

 

the only cats ive had that smelled like rotten eggs when bad was on my 79 ta. the design of the newer cats was suposed to stop that. i dont think its your cats.

 

should have gotten dogs instead of cats

 

Anyways the smell only happened that one day.... I noticed the smell hasn't come back. But my mileage is slightly lower, so I'm thinking its probably the cats. No change in driveability or performance though

some funny posts in here I'll admit

 

The only time I smell any odor is after I have hammered down a couple of times and then pull into the garage.
