Does the car start if you push the pedal all the way down. If you have your tps calibrated it will cut all fuel. Also how does your tach look, injectors timing, and map look through megatune? It could also be a stuck injector. Pull them real quick and see the spray patterns. Make sure its not something mechanical before you start messing with your settings. My money is something is not hooked up right or injectors stuck. Good luck. 832-444-4540 Ted
