Why does my 2000 mazda protoge smell like gas emissions inside my car? It seems to be comin from my heater vents.

Asked by Nov 20, 2014 at 11:42 AM about the 2000 Mazda Protege LX

Question type: Maintenance & Repair

it was just running bad from fouled up spark plug.  I just replaced them and the car runs
better but still runs slightly rough. The engine smells like emission like it's running rich.
Do you know what could be causing that?
