problem #2

I experienced a terrifying event of sudden acceleration. I was pulling into a church parking lot yesterday morning and had almost come to a full stop when suddenly the engine revved and the car took off (a witness said the horn beeped as it happened; I don't remember, I was so busy trying to control the car and the engine was loud, like a teen-ager in a drag race). I kept braking and turned the wheel sharply to avoid hitting the fence in front of me but couldn't get it to stop. It was like it was demon-possessed. I hit a glancing blow to a transformer and a tree and hit two backyard fences. A metal pole of the fence got caught in the right tire and I stopped before going into a swimming pool. The engine quieted down somewhat simultaneously. I'm not sure yet whether it happened because of something installed in the car originally as it has not yet been investigated by our insurance company but we haven't had any recent repair to the accelerator or had any serious problems with this car before this.

A loud rumbling noise was heard at 2000 rpms. The vehicle was taken to the dealer several time, however they provided no solution.
