Not all the time but from a stop when I try to accelerate the engine just drops out then trying to take off or some times just die. Also when I pull up to a stop it sometimes does it as well. It doesn't throw any codes. I had takin it to the dealership and they changed the fuel pump the computer all the sparkplugs coils and wires. Also tried swapping out the throttle body and gas pedal along with the fuel rail. Did compression checks, nothing fixed it and everything checked out OK. But its still doing the same thing. In the cold it seams to act up more then when its worm out. When I say cold I mean 10 degrees Fahrenheit. You have to be very careful pulling into traffic because your not sure if its going to go or not. Has anyone experienced anything like this and could send me in the direction of getting it fixed. Help please!!!
