Just started the other day, i live in Alaska so i'm not sure if its an effect of the cold or not but either way just started yesterday. When the vehicle is started cold it will kick over the RPMs will drop really low as if its not going to start then jump back up to normal. Then during shutdown theres a slight shudder after the key has been turned off and the engine has stopped. However these problems are alot less noticeable or not even there after the engine has ran for a while. Is this something i should be concerned with?

Do these trucks have a IAT sensor? I know on my Mustang, it would do something like that when the IAT sensor was bad/dirty
If the truck does have a IAT sensor, it will be located on the intake tube between the air filter and throttle body.
