I have a 97 2.5L v6 Avenger, and everytime I come to a stoplight with my windows down, I start smellin theis rotten egg smell. The car drives fine, theres no driveability problems, but it just stinks at stoplights. Does anyone have any idea what the problem could be?

Its your Catalytic Converter going bad. They have that smell as they start to go bad. If you let it go you will notice a Decrease in fuel mileage!
