[Vanie]

...sitting at a stop light with your? driving down road came to a stoplight stopped put foot on brake this was on a very steep grade all at once it was as if someone laid a brick on the gas even with my foot on the brake it would not stop somehow i managed to put the car in neutral the car still was accelerating it finally stopped we took it to the dealer they could fine nothing wrong with it this happened twice more they said they called ford and were told there was nothing wrong the 4th time it was because i was sitting waiting to turn in the store as i gave the car a small amount of gas because it was only about 100 yards to the door again the car took of as if i had floored it needless to say this time the building stopped me i was charged with the accident because "there was nothing wrong with the car" anyway i am very curious to see if this has happened to anyone else i will not drive the car and wont sell it because someone else could be hurt or killed im sure im not the only one this has happened to thanks for listening
