Question about 2003 Ford Windstar
I can flutter the gas pedal and the rpms will go up, but it back fires through the throttle body and runs rough. If I take my foot of the gas pedal it will die.
Connect a fuel pressure gauge to the fuel line, start engine and record pressure, switch of engine pressure should hold , if not check leaks at fuel regulator, injectors, and fuel pump return valve,if ok check fuel pressure and flow , if pressure is low replace the pump , if flow is low replace the fuel filter, check fuel pump has reserve pressure by quickly clamping and releasing the return line the pressure should up to 50 psi or more.
