Hey guys I have a 2010 v6 4.0 Mustang that has trouble starting when it is cold and windy, then after it starts it shakes and has trouble idling until it warms up. This only happens when it is around 0 or below cold any help would be appreciated!

I don't have a lot of experience with zero temps in Texas but I'm guessing a block heater would help.

I don't think the iac valve would be affected by the cold but it could be coincidental.
I bet it has something to do with the battery. How old is it? Before you start it turn the key on and wait a few seconds then crank it.
