Car won't move forward when I accelerate the gas pedal for a moment then it jump forward and become drivable. This happened very often in the morning.

While driving, the vehicle would suddenly stall. It happened at low speeds up to speeds near 50mph. Everything would be fine, but then it was like there was a stumble and the engine would shift to idle, causing the vehicle to a stop. The engine would not cut out, but would only idle. If we turned the car off, waited a minute, then restarted the car, it would drive fine (until the problem repeated itself at another random time). The dealer made several attempts to repair. They first changed the throttle body, but then it happened again to us within 30 minutes of the repair. They next changed the accel pedal, but it again happened as we pulled out of the dealer across traffic leaving us vulnerable to a severe accident. Finally, they replaced a ground wire for the accel pedal and the problem "seems" to be resolved. I say "seems" because the car does not drive like it did before the problems started. There still seems to be a stumble, but no stalling. Since the car does not stall, we are not taking it back to the dealership, but we get very nervous each time we feel a slight stumble. This problem seems similar to the "drive-by-wire" problems experienced by Toyota drivers and has potential for a severe accident, so I thought it was worthy of reporting.
