    Gas Mileage

    Have you switched brands of gas? That can definately sometimes afect mileage. Or have you put in an new air filter? That is another thing that can help out mileage. Other than that I really have no clue.

    Re: Gas Mileage

    Unless you changed something like fuel, oil, some sort of parts on the car, etc. it could be a plug went south on you, or maybe an ignition wire, coil, or even an O2 sensor.
