I recently replaced my fuel filter then fuel pump and after that my fuel injectors. I used accel fuel injectors. At first my car drove fine, but now i can hear my fuel pump and my car is sputtering as i drive and i have to really put my foot in the gas to really get somewhere. My check engine light is not on but i do have a vacuum leak somewhere. Can anyone please help me. I'm in the marietta, Ga area if you're local
