#1

Why would my car emit an exhaust smell upon decelerating? It happens when I get off on an exit.,


#2

Does it smell like rotten eggs? If so then it could be a poorly designed catalytic convertor.

I’m trying figure out how you could smell the exhaust of a car you’re driving?


#3

That is a bit of a mystery to me, also.
