We don't know. Neither do you.

You need to do some diagnostics to determine what that is before you just start replacing stuff.

Did you ever do a compression test?
What about inspecting the vacuum hoses yourself? (remember that some may be under the intake manifold)
Did you hunt for vacuum leaks with an unlit propane torch?

If you suspect the IACV, have you done the shop manual-prescribed test for it? (It's not that hard - all you need is a multimeter, IIRC)

Put a DVM on the TPS and see if it reads smoothly through the whole range, and if it reads the correct value at closed (some are adjustable)

Try this:

+ YouTube Video
ERROR: If you can see this, then YouTube is down or you don't have Flash installed.

IIRC, the TPS on this engine is adjustable, but is also pretty simple. It's more like a switch than a sensor. It has four or five positions for which there is an expected resistance between its various pins. It's not like a rheostat where the resistance is continuously variable.

This might be worth checking too, Ghetto. Get you a copy of the TPS test procedure and check it. It's really not that hard, but it does help to have an extra hand or two.
