Its been really warm here. But funny you say that when it started cooling off I decided to check it and the choke linkage was screwed up. I fixed that now it works like a champ.

Start with the factory shop manual dimensions, then have someone start the truck while you're underhood. As soon as it fires try opening and closing the choke door a little (like the thickness of a pencil lead) to get the best operation, and then try to bend the linkage to get that setting automatically.
But just check it before going crazy, you could well have some other problem entirely.
