it may be idling too low...there is a re-flash to fix that,usually

idles at 500 rpm when warmed up in gear, park is maybe 50 rpm higher. re-flash is that a pcm reprogram?

If your truck's mileage is getting up there you may wan to clean the MAF sensor. As they get dirty they are unable to detect airflow over them.
It worked on mine. Might as well descreen it while yourat it! lol( contact cleaner from Radio Shack ) Best of luck |

They also sell MAF sensor cleaner at NAPA for this specific purpose.
