What would cause my car to backfire and have no power when I hit the gas? I doesnt do it after it runs for a bit but it still doesnt have power like it should. I have already changed the plugs and wires and it didnt help.
Model: mustang gt
Engine: 5.0L V8
Changed the plugs and wires and ran a fuel system cleaner.
This sounds like a fuel problem. First try replacing the fuel filter. If this does not help, test fuel pressure with a gauge. If your fuel pressure is lower than specified, replace the fuel pump.
