1995 Chevrolet Monte Carlo Q&A
1995 Chevrolet Monte Carlo Question: Heater causing gas odor and low mileage???
You need to get this looked at ASAP. Sounds like you have a fuel leak under the hood such as a ruptured fuel line. Obviously, if you are leaking fuel, your mileage will suffer. You smell it with the heater because the intake for the heater is right behind the hood and in front of the windshield and heat usually pulls air from outside unless set to recirc. A/C on max will use recirculated air automatically which is why you don't smell it then. But seriously, get this thing to a mechanic before it decides to burn to the ground. - Rojo1
