Your catalytic converter is going bad.

Your cat, or someone dropped some rotten eggs in your vents on Halloween.

 

Bad Cat......

 

thanks! hmmm should i look for a stock one or a free flowing one?

 

Rotten egg can also be sign of sulfur...bad or swelling battery.

 

I agree. I think it's your battery.

 

usually a bad cat has a sweet smell

 

I've had the rotten egg smell... but intermittently... now i have no cats... don't go replacing the cat until you get a code for a bad cat.. po420 i believe..

and if it is your battery.. wear some goggles when handling it.. i've seen batteries spray..

it can also be that you're running rich and an o2 sensor is on its way out..

 

Ive smelled both cats, and batteries that smell like rotten eggs.

 

sulfur... its everywhere.

 

now to think about i recently tried to recharge my battery after i put my system in, started to take 3sec to start the car.....ill change the battery first since its the least expensive. thx

 

you can always visually inspect it for leaks and have it tested at autozone to see if its still good.. no need to just go throwing money away!

 

sorry,
