One of the instinctive things was to tap the pedal to “unstick” it, but if you’re decelerating that can cause issues, especially if it doesn’t work. That's not unintended acceleration, that's a sticky throttle cable that needed to be replaced. Or possibly a weak return spring on the throttle mechanism. I'm curious why you didn't take it to a mechanic and get it fixed (any mechanic could have fixed this, not just Toyota techs).
