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,

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.

SOURCE: rotten egg smell in cab but not all the time

Rotten egg smell means Sulpher is present somewhere. Check for exhaust leaks. this usually means exhaust is creeping into the cab. You may have a blocked or leaking catalytic converter.

When you say smell like exhaust, does it smell like rotten eggs (sulfur)? If so, could be catalytic converter clogged up.

Alternator burns out

You have a faulty battery, that's probably what killed the other alternator. The rotten egg smell is gases coming from your battery. Change the battery before you cook the second alternator.

Car runs ok, but gets hot and rotten egg smell comes out of the exhaust

If car runs okay with egg smell, its normal and working the way it should, if car is running poorly and the rotten egg smell has gotten worse, its a sign that your exhaust catalytic converter will need to be replaced. good luck!

Rough idling, poor gas milege

Usually the rotten egg smell is a clogged CAT. Is the engine light on and if so did you retrieve any codes?
