Update: I replaced the IAC today, wasn't to bad of a job, other than it was on the backside of the throttle body and we just had the intake manifold off last week to do the coolant return tube that ran under the manifold from the rear of the motor to the water pump.

How importent is it to change the gasket when cleaning the IAC? I cleaned mine 2 weeks ago after a thread came up. When I took mine off I didn't find what I thought was a gasket, but I could feel some rubber seal on the throttle body side. So I just cleaned it and put it back on. Now seeing SDDESIGNS picture I see what the gasket looks like. Since cleaning the IAC my truck does idle more smoothly. I have also noticed my idle is higher in RPM.
Should I take my IAC off and replace the seal? or should I be fine?
Thanks.

Well it hit 32°F this morning and started like it was 70°F out, we should be getting some lows in the 20's over the weekend, so time will tell!

Well it seems to have fixed the cold weather stumbling, we had a successful start without any issues at 27°F this morning! From this point on I guess no news will be good news!

Yep. My 97 f150 did it at that temp. Once I cleaned out the IAC with intake cleaner spray the problem was gone. The IAC was way easier to get to on the 4.6.
