general problems of the 2008 Mercury Grand Marquis

I was driving in town and several times when I slowed down to stop at a stop sign or corner, after braking my car accelerated by itself. The engine revved up and made the car jump forward. I had to slightly release the brake snd brake harder to stop and avoid going into the intersection.

The car will suddenly and without warning accelerate to 5000 rpm's. Had throttle body and mas replaced which seemed to help. However, it still happens once in a while (once every 3 weeks average). Usually happens after shifting from park to drive and driving forward at low speeds (around 5-10 mph). Hasn't happened at higher speeds. Was told by one mechanic that the computer is defective???.

When reversing out of driveway car accelerated on its own. Pressed brakes but car still moved backwards. Have skid marks in driveway to show for it. Threw car into neutral and turned off engine. Restarted and everything seemed normal. Drove car on trip and when reducing speed to slow down by pushing on brake car again accelerated and nearly hit another car. Again threw car into neutral and turned off engine. And again when restarting car everything seemed normal again. Wife is extremely afraid of driving car. Took car to dealer where it was purchased and was told that it may have been that I pushed the brake and gas pedal at the same time, this however, I believe is not the case. Dealership however kept the car for further investigation as to what the problem may be. Will hear in a day or two,.
