Volvo Gas Mileage again

Discussion in 'General Motoring' started by Geoffrey Collins, Sep 4, 2003.

  1. Please advise me here:
    I have a 1989 740 GL 8 valve no turbo.

    I have already changed the oxygen sensor and the fuel pressure regulator
    and the air flow sensor but

    still poor gas mileage-- 12 mile to the gallon.

    Any more ideas will be welcome . Thanks

    Geoff

    Have you checked for leaks in the fuel lines or tank and for dripping
    injectors? Unless the engine is running like total crap it seems fuel must
    be going somewhere.
