rotten egg smell coming through the vents
It only does it when the car gets hot and has been driven 20 mins. or more. It doesnt matter if the air is on or not. There is not a rotten egg smell anywhere outside the car. I can't figure out where it is comming from. please help

agree that the catalytic converter is bad, futhermore; is the engine running cool(temp gauge toward cold)? if so replace thermostat.
