general problems of the 2001 Lexus ES300

2001 Lexus ES 300. Acceleration issues the consumer stated when his wife started the vehicle, it immediately went to full rpm, probably around 6,000 plus. Her feet were flat on the floor. She had not put the gear in reverse to back out of the garage, nor had she touched the brake or the accelerator, when the rpms began acting erratically. The consumer stated only a computer failure could have caused the rpm to instantly increase in that manner. The consumer stated he went to the garage to see what was going on and was able to turn the vehicle off. The consumer re-started the vehicle and it behaved in a normal manner.

While driving the car would speed up on own without pushing on the accelerator. I found my car going from 40 to 60. In park position the car will rev to high rpm but if I am in drive mode it will just accelerate. I took it to Lexus and the technician says the idle speed control valve was not working and the repair work would be $500.
