Paul, if its anything like the stock v6 it should be just remove and replace. The tps shouldn't Need any special install process.
The iac may use a cleaning of the orifice it inserts into.
Again this is my experience from the stock v6 throttle body sensors, but I don't see how the 3800 would be any different.
Ryan from sinister would be the one to ask though!
