brian i told you today when you came by my house. The IAC is the idle air control (im not 100% but im pretty sure thats what it is) and your TPS is a throttle position sensor.

I work at a repair shop and we see this a lot. First of all, remove the air intake duct (hose running from filter to the throttle body) and look inside the throtle body. Ifit is dirty; black looking, try claening it with carb cleaner and an old toothbrush, but do it while the truck is not running. If that doesnt fix it, try unplugging the IAC and see if it runs better, if so thats the problem.
