The thing that bothers me about un-intended acceleration claims, what is wrong with the brakes? The fronts easily will hold a stopped vehicle even with the rear tires spinning away. That is common at the dragstrip aka the burnout. KM

+1 this is what I suspect is happening. It's possible some people get panicked by the perceived loss of braking when the trans downshifts.

Just got into a minor fender bender.
The lady was stopped, waiting to turn left.
I slowed down to a stop with my foot on the brake only. The truck revved and launched forward.
My foot did not hit the gas, and the carpet was not jammed under the pedal.
Has anyone else had this happen, or have any idea what caused it.

The only way the engine can accelerate is to get more intake air, assuming there is Gas to mix with the air.
Either by foot or a fault that opens the throttle plate or an intake air leak.
The MAP Sensor detects the change in manifold vacuum to add the fuel.
