pretty sure you didn't get the timing quite right when you replaced all the parts. also, with all that work you could have messed up a vac line. check all vacuum lines, that can really screw up your idle. Also, I am not 100% sure, but I think your truck may have something called a spout connector. If you don't disconnect it when you are adjusting the timing, you will never get it right. disconnecting it takes the computer out of the equation while you are timing it. If you don't disconnect it, the computer is trying to compensate for everything you do.
