I had a problem with my 99 ( 5.9 4wd ) that was driving me nuts. When I would first start it, it would run great. But then as it warmed up, I would have to throttle it up to about 2k on the tach. Once the temp guage got up to normal operating temp, I could let off the throttle and it would run fine. If I tried to run the truck before that, forget it. I replaced everything coolant related, it was due, and the O2 sensor before the cat (upstream). Pretty sure it was the O2 sensor that fixed the problem. Maybe try that.
