sounds like your cat is going bad. I've have the same exact thing happen, and also check to make sure you are not running pig rich.

sorry pig rich is a slang.

More like if the car is running rich. Rich = raw fuel that's not burn inside combustion chamber leaving the engine. Sometime known as black smoke from tail pipe.

I would check your O2 sensor to make sure it is responding correctly or your engine is not having vacuum leak in return causing the ECU to enrichened the fuel mixture.

i know there are no vac leaks
and im sure the o2 is ok i dont have any codes being thrown.
and theres no smoke just a very strong oder of gas.
anything ells that might cause it suck as clogged injectors or somthing.
if i remember reading correctly if there clogged they can spray extra fuel is this true?

Are u smelling raw gasoline inside the passenger compartment even with windows closed. If so you might have a leaky injector. That will cause ur car to run rich and rotten egg smell from ur exhaust. Have that check out asap. Cuz u can get an engine bay fire. Ask me how I know. LOL.

not to much when the windows r up only when there down or when outside of the car one once or twice ive smelt it inside with windows up.
most of the time its like when i have windows down and i come to a stop or right after i let off of boosting hard
