I have a 1990 cad seville and it misfires,at idle and all speeds..There is no check engine light and there are no codes..It has new wires,plugs,cap,rotor,fuel filter,air cleaner..It only has 68,000 on it..Does anyone know what the problem could be? im thinking it could be a fuel injector..Is this possible?

Any way to check the Fuel Pressure?

How about the Pressure Regulator, is it leaking?
