The best way to diagnose the TPS is to simply unplug it. Try pulling the connector out and driving around as normal. Unless you are doing quick throttle openings you should not even notice a difference in performance and it definitely won't hurt anything. If you cannot recreate the bucking situation after a while then you can safely assume the TPS is the culprit. If bucking does continue you will at least be able to rule it out as the problem. (been there...).

Post back with results after you try this.
