Hello I have a Obd code p0170 i am thinking its a fuel pump issue in high speed when I press the gas pedal I hear sputtering . I changed fuel filter, fuel pressure regulator, all fuel injectors, map sensor and oxygen sensor front . Still the code pops up I checked the ohm on the pump and it is 0,9 . Can’t see I have found any vacuum leaks .
