I just had the spark plugs and fuel filter replaced in my 08 expedition and after the engine does not run as smooth as before. We checked the fuel pressure and is 60 at start and 70 while running. Does anyone know what the fuel pressure is supposed to be? The old spark plugs were really bad and so was the fuel filter so we are thinking that we the new one the fuel pressure might be too much and that is why the engine is not running as smooth.
Any advice is greatly appreciated.
