Hi Scotty! I have a 2005 Pontiac Grand Prix 3800 series 3. When you push the gas pedal when diving the car it stumbles. It's like it dies and starts back up. just like you cut the key off and back on. Changed Crank sensor, ICM, MAF, New plugs and wires all new coils, but it still does it. It's been doing it a few months but has gotten worse. No check engine light is on. So do you have any clue as to might be wrong with it. Thank you vey much.

Change the fuel filter (if equipped) and pressure test the fuel pump.
