My car bucks/ hesitates at cruising speed when under a load. Tested fuel pressure. It reads 55-60 when you turn key on it starts fairly easy. when you hit accelerator hit wuickly drops then builds back up. Also when you shut off car the pressure instantly drops to 0 . From my understanding it is NOT suppose to drop instantly. What does this sound like injector. fuel pressure regulator, pump going bad?
