Hi Eric,

It's probably not the TPS if the car was idling okay before you cleaned the TB. Can you hear the switch click when you move the throttle? The problem is likely to be related to the IAC. When you cleaned it, would the valve rotate back and forth freely? Are you sure that all of the vacuum hoses are connected? It's been a while since I've looked at a 16 valve, but they're basically the same as the 8 valves regarding the things that you're working on. The bucking when coming to a stop is probably being caused by the high idle. The base idle screw (big black one on the bottom of the TB) won't help with that high of an idle.

Check it out and let me know.

Dave
