Default Rotten Egg Smell???

I have almost 82,000 miles on my C5 and I am starting to get a rotten egg smell inside the car when I am at a stop. This is most common after I have gotten on it a bit :D

Dying Cats??

Car seams to run fine and it just passed the sniffer test here in DFW.

I have heard that rotten egg / dead fish smell can also be a symptom of an ECU on its way out. In this situation, the smell comes from leaking capacitors eating away at the circuit board.

I did not specifically hear this about Corvettes. This became a problem with a lot of the first generation Mitsubishi Eclipses, Eagle Talons, Plymouth Lasers, and Mitsubishi Galant VR-4's after they were about 4 - 5 years old. Heat would definitely be a factor in accelerating the problem.

Check if you are running a too rich air/fuel ratio. :)

Go to your local Self-Chem store and get some Rat Sorb. Soak a cotton ball in an
old plastic cap and leave it in your car over night. The stuff works until you find
the cause

I am not sure of the root cause, but it is my understanding that a rotten egg smell is the result of an overly rich mixture going through a catalytic converter.

High sulfur content in your gas (well, not your gas, your car's gas. Although I guess it would apply to your gas as well...) will give off a rotten egg smell.

Have you checked if your woman took the car for shopping, while you were asleep? Maybe she lost an egg in there!!

Try a different brand of gas. That sometimes takes care of the problem.

SPS has it right:

"I am not sure of the root cause, but it is my understanding that a rotten egg smell is the result of an overly rich mixture going through a catalytic converter."

Hey, I do remember seeing a TSB about that a while back. Do a search on the archived topics. It was atleast 6 months ago when I saw it..
