This may not be your problem, but check out the motor mounts. I've seen a broken motor mount allow the engine to move enough under acceleration to bind and jam the throttle linkage when accelerating from a standstill, especially with full or nearly full pedal. When this happens, you let up on the gas and the car just keeps accelerating! Scary feeling.
