V-6 IDLE PROBLEM

2000 Mercury Mountaineer • 6 cylinder 2WD Automatic • 106,000 miles

2000 Mercury Mountaineer V6. Cold startups idles rough and stalls out in colder weather until engine temperature reaches normal. Afterwards, it seems to run fine.

Is this an Idle Air Control Valve problem? Would cleaning it with carb cleaner help? Exactly where is an IACV located? Do you have any other suggestions?
Thanks

Try cleaning it and see what happens

Disconnect the battery ground cable. For additional information, refer to Battery.
Remove the accelerator control snow shield.
Disconnect the idle air control (IAC) valve electrical connector.
Remove the IAC valve and discard the gasket
