This is the 3rd thread I've read with the same issue but not one of the OPs have come back to say what the issue ended up being. I changed COPs and plugs Friday and the truck runs great now other than low (200-250) RPM at a stop. Maybe I just need to let the computer relearn idle...

You could also clean the throttle body, I changed my plugs and the truck still had some rough idle problems and I cleaned my throttle body, it was nasty runs like a champ now
