Definitely check the battery voltage first. A weak battery can make these trucks seem possessed. If it's not the battery, it sounds like the problem is only in open loop.. once it hits closed loop, it idles ok.
I would look at what the code is, (do the key dance) then hook it up to a scanner and monitor the sensors that are used in open loop like the IAT sensor and the coolant temp sensor.
