When the truck is cold it's running on a default map, known as open loop. It doesn't rely on the oxygen sensors to adjust the mixture. When it reaches a certain temp (it's like 180* I think?) then it goes into closed loop mode and uses the oxygen sensors to adjust the mixture accordingly. Your truck isn't warming up, so it's staying in the default open loop and that is causing you to get crappy mileage. Again, I don't really get how you didn't figure this out on your own. You mentioned having a shop, and I see your truck at whatever the mustang place is called on lyons and johnson when I drive that way.
