Another thing to check, if your truck has it, is your IAC (idle air controller). My truck actually decided to spring the same problem you're having (though I have an engine light on). It was running super rough (I could even feel a cylinder misfiring) and didn't like starting. I swapped the plugs and used fuel system cleaner and it runs almost perfect now. It just doesnt like idling when cold. (Sound somewhat similar to yours?)
I've been told that the IAC can be the cause of this. If the truck runs fine except for your idle, check the IAC...that's my next step!
