Why was the head gasket replaced?? any other work done on the car, or tinkered with??? Do you service the car properly??? (plugs, ingnition wires, fuel filter, air filter, fluids) could the fuel injector system be dirty and clogged??? can there be a fuel leak?? or bad oxygen sensor????


: Recently had head gasket replaced. Ever since, gas mileage has dropped from an average of 20 mpg (city and highway combined) to 14-15 mpg. Why is this and how can I fix? Thanks very much. Happy Holidays to all!! DJD in KY.
