Without proper computer diagnosis it is hard to say exactly what is wrong with the engine. Just from your symptoms and experience with this vehicle I would suspect a failed throttle position sensor. But there should be codes stored in the engine and ABS computers that will point to the actual failure. A full scan of the computer modules is the first step towards a repair.
