hold the TB up to the light and see if you see any light coming from around the butterfly. Could be a leak there. If not, then take it off and put it back on the intake manifold to make sure it seals up right.
Also, check the 2 sensors on the side to make sure they are on all the way?

Unplug your IAC and TPS and turn the key on but dont start, wait a couple of seconds and cut the key off, plug them back up and turn the key back on, wait a couple of seconds and then start the engine. This will put everything into a learn condition(the computer will think you cahnged sensors out) and after a few minutes it will relearn. Dont ever say I never done anything for anyone

The easyest way so you know it a vacum leak is get you some starter fluid and spray around averything and if the RPM's come up then you know you gave a vacum leak!

If you have a friend that smokes it is easy. get a small tube, crack the TB and slide the hose thru it. Now tape up the inlet of the TB so no smoke gets out the front. Then have your smoker friend blow smoke thru the tube, and you should see smoke come out wherever there is a vacuum leak (assuming there is one).

When you have the car idling did you disconnect the intake and look at the throttle body make sure that the cable isnt holding the blade open just a tad may need to adjust your throttle body cable. Just trying to think of everything I checked when mine was doin the same thing, now its doin fine.
