My 2004 chevrolet malibu classic usually starts in cold weather but gives me trouble when it is warm outside. If it is warm outside the car has problems starting and will sometimes die while coming to a stop. It has lately been getting extremely bad gas mileage. Im only getting maybe 250 miles a tank. I have replaced fuel pump relay, fuel pump, spark plugs, fuel filter, fuel pressure regulator, and was told to check asd but it is built in with the fuel pump relay. So I do not think it is that. Also when the car is not starting I do not here the fuel pump prime, which thought could be bad wiring but bad wiring shouldn't cause bad gas mileage. Was told by one mechanic it could be a bad sensor, but which one would give all of these problems?
