I have a 99 sport with a 3.9 and when I stick it into park from drive or other gears the RPM's drop almost to 500 and sometimes lower, to the point where it almost wants to kill. I have had it to the dealer and they say its the idle speed motor that needs to be replaced and they want to charge me $270 for that to be replaced. I am not real knowledgable about all engine components and so on, but does this sound right or could this be some simple adjustment they are leaving out?

When I bought my V8 TB for my V6 it came with the Idle Air Control valve (IAC) and TPS sensors alredy on it and I only paid $190 for whole thing.
You might try cleaning it, this from Bernd's site

How to Clean the IAC Solenoid:
This is recommended at every Tune-Up to prevent excess carbon buildup on the IAC plunger. In some cases, you'll notice a slightly erratic idle quality. This is the first step in taking care of that problem. IAC = Intake Air Control (Solenoid).
Remove the Air Hat from the Throttle Body
Disconnect the sensor harness from the IAC Solenoid (Rear of Throttle Body)
Remove the two Torx-25 Screws
Remove the IAC Solenoid (Be careful not to lose the rubber O-Ring)
Spray some Carb/TB Cleaner in the IAC port on the Throttle Body and let it sit
Spray some Carb/TB Cleaner on the tip of the IAC Solenoid and wipe clean (Do NOT forcefully twist or push the plunger - You will damage the Solenoid. Wipe very gently.)
Spray a little bit more Carb/TB Cleaner in the IAC port on the Throttle Body and wipe clean with a thin/lint-free rag
Reinstall the IAC Solenoid (Make sure you don't lose the rubber gasket on the solenoid)
Reinstall the sensor connector and airhat
Start the engine and let idle for about 1 minute.

I replaced the IAC valve in my 99 sport for about $45. You can get the part at your local auto parts store, I'f they don't have it they can get it within about 48 hours.
