What's your problemm?chevy colbalt smells like rotten eggs


The rotten egg smell usually occurs from time to time. It comes from the battery being charged by the alternator. However, if it smells continuously there is a problem. It's likely that your alternator is overcharging the battery. This needs to be looked at soon. The alternator will need to be replaced or repaired. Hope this helps.

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?

SERVICE ENGINE LIGHT


The sensor will be external and cats don't always smell like rotten eggs when they go. Also check as you will probably have a post converter sensor as well that sends a signal back to the main computer.
