Have you disconnected the PIP when you time your truck, if not then that could be the problem.
Also try checking your PCV valve, and your filters under the hood. These could all cause the problem you describe.
I know mine definitely runs better after the other morning. I decided to do a little test since mine is bogging down, and has a bad hesitation when you take off. I disconnectde te vacuum line off of the EGR valve, and it runs 100% better. That one thing cured all of the runnning / idling problems I have been having. But I replaced the EGR & EVP sensor when I dropped the engine in the truck 2 years ago.
