Don't think Directions doesn't say in FSM etc. but not digging thru them right now to check.
I would wait for engine is warm because ECM wants IAC to boost idle when engine is cold.
Is common to see ~ 1500 to 2200RPM weather temp under 10°C. Is colder like ~ 0°C then more RPM like ~ 2200 until you push the throttle pedal later. Even then may not idle "normally" until engine is warm enough.
But you need to make sure if IAC etc isn't the main issue or resetting the idle stop will be problems and car won't idle right or stall.
Plus butterfly should never be closed fully. If you do, then butterfly can get stuck or damage the TB. Being able to close all the way mean has vacuum leak or other problems leaking air passed/"below" the TB.
V6 EGR and other vacuum operated things can fail and some are hard to find. See my Cave,
Vac Leaks for a starting point.
