There's one of two problems:
A mechanical lock up, or
Electronics can't follow the load/unload of the engine quickly enough.
I doubt it's a lock up problem...that would likely kill the engine. Take a look first at the TPS sensor and see it's voltage as it falls and raises. Also, what happens when you slow down, in gear, as opposed to slow down and throw it into neutral?
Also, is the IAC pintle able to move freely? It may be sticking.
