How long since the plugs and wires have been changed? That is the first thing that I would suspect. I had the same problem and after changing plugs, wires, air filter I still had the problem. Tonight I tried the SeaFoam through the PCV tube. I used about a half of a can. Let it sit for 15 minutes and then took it out for a spirited ride. I had the RPM'S up near 5K a few times. There was some smoke, but no where near as much as some see. The idle has smoothed out and it seems a little peppier. I will see in the next few days if it stays smooth. It is still a little rough, but a tremendous improvement over what it was. What year is your truck? How many miles? IF you have a separate Idle Air Control it could be the culprit. We need more info to really determine what the causes might be.
