I am right in the midst of this same problem. I changed the IAC and the TPS. It seems to be doing better, but I haven't had enough time to test it out. I know another member said he had to change the Fuel Pressure Regulator. You may want to try the TPS and then the Fuel Pressure Regulator.
ALSO - I have no Check Engine Light either.

Go to Autozone. Rent (for free) their fuel pressure tester. Easy to use.
Measure FP. Spray propane, or ether around base of manifold.
If pressure isn't 34-39 (steady) and if idle is affected by the manifold test, you've found the source of the problem.
Negative on the above two, and it may be the TPS. A simple volt/ohm meter will show if TPS sensors aren't consistent.
