High Fuel Consumption
I used to get 15-18 MPG city driving and 20-25 MPG free way driving in my 1990 BMW 735 IL.
Now I am getting only 13 MPG city driving and 15 MPG freeway driving.
Sometimes car runs smooth and other times there is a miss during idling and driving slow or fast.
I have installed new spark plugs and a fuel filter, but fuel consumption has't improved. Could someone help.
Regards
Bernard
