That smell is a byproduct of the catalytic converter doing its job, if the smell is really excessive the engine may be running rich due to bad O2 sensors but if it's running good I would have the exhaust system checked for leaks or a damaged tail pipe directing exhaust in the wrong direction. I hope this helps. Take care.

This is a normal condition for all american made vehicles, as most of them are rotten.

Hey there riddick,
That rotten egg smell is a problem with your catalytic converter. Too much back pressure is not allowing your engine to run normally.
I'll bet its been getting hot too.
Warning: For your own safety, until this is resolved, do not look under or stick your head under the car with the engine running. I've been in a vehicle when a converter with these same symptoms blew apart at the seam. Made my head hit the roof. If it happened a few minutes earlier I would've gotten a faceful of freshly flattened converter. So be careful.
To tell for sure about the problem, try to get it to an auto parts store that does free code readings from your On Board Diagnostics. There should be errors referencing the engine, O2 sensors and emissions. The exact diagnostic codes with determine your next course of action.
Be safe,
Mike

Sounds like a bad catalytic converter. If you were feeling a lot of heat under your feet while driving (before it stopped completely), this is one of the symptoms of a bad catalytic converter. The smell is sulphur backing up and not efficiently moving through your car's exhaust.

Your catalytic converter is plugged up,
If you check the exhaust output at the tailpipe you will find it restricted.
Let me know if I can assist further.
