Why does my car smell bad when I accelerate hard?
The sulfur smell or ‘rotten egg’ odor is caused by high amounts of sulfur in the gasoline being used in the vehicle. the exhaust system. When high sulfur fuel is burned, there is a chemical reaction in the catalytic converter causing the sulfur to oxidize.

Stagnant water leads to mold, which cultivates within the Styrofoam insulator that surrounds the evaporator. When you drive up a steeply inclined ramp, some leftover water likely runs to the back of the evaporator, exposing the smelly, rotten debris and mold.
