What causes my car to smell like exhaust fumes when there is no exhaust leak?
In cold weather with the windows closed, when I'm idling, parked or waiting for a
light, the car sometimes fills with the smell of the exhaust. It seems to happen
more so when it is cold and windy. Another mustang owner told me it was the ,
"charcoal canister". My mechanic looked it up and said it is called an evap
emission control canister. I should mention that when this happens you can
even smell it outside, sometimes very strongly.
Does your mustang still have the factory catalytic convertors? Some owners remove them and add straight pipes for more HP. If so you will get that smell.
