if you have A/C then you have A/C gas leaking if not chack your automatic tranny fluid it must very old and leaking and brownishinstead of redish,that,s when they smell like rottin egg

cat convertor leak is the only other can smeel like that ,check for leak around the gasket or hole in it

Change your oxygen sensor. When they go bad the mixture gets richer and this causes the rotten egg smell coming from your exhaust.

I've never heard of leaky A/C or old tranny fluid causing it!?!?!

That's a new one on me!

I had that same smell happen to my Geo Metro but it was caused from a failing catalytic converter.
