The auto surges forward as I'm trying to stop either at a stop light or parking spot. This has happened 3 or 4 times and my mechanic said the only way to fix it would be for it to happen while he was driving it. There's no pattern to when it happens but it's scary and I'm afraid to let my wife drive it. It happened yesterday as I was coming to a complete stop before entering a 2 lane highway. The other times it happened was pulling into a parking spot and applying the brakes to stop. I now put the car in neutral when it happens and the engine is racing away. Putting my foot on the brake isn't enough to come to a compete stop. I've read other complaints about this happening with no honest answer for correcting it. Mostly trail and error. Toyota has to know the answer but there's no service bulletins from them. I'm afraid that it's going to cause a serious accident or bodily injury to me or my wife. Nhtsb has got to look into this ASAP. P. S. My car has 71000 miles on it.

The engine started cold and revved to 2500 rpm and then oscillated between 2500 and about 3000 rpm and never slowed down. I put the car in drive and drove it the block and a half to my house using the brake to stop at the only stop sign on the route but stopping was difficult. The next morning I experienced the same ultra-fast idle and drove the car on an errand that was about 2 miles distant. The same pattern persisted but the brakes were heating up and smelling from frequent use in keeping the car within the city speed limit. It also stressed the automatic transmission while braking aganst the fast motor. I started shifting from drive to neutral and coasting to control the speed while the engine speed oscillation continued. I parked the car back home and had a tow truck take it to marietta Toyota where the diagnosis was to replace the idle control motor at a cost of $669. 00 less a $99. 00 negotiated discount. That service solved the problem but the problem had the potential to overheat the brakes, cause one to coast in neutral without ideal control of the car in an emergency, etc.
