1999 7.3 Powerstroke surging

I 've got a 99 7.3 that has started to surge just under normal pedal pressures, not under acceleration or load, because then it spools nicely and accelerates with no problems. Whats up with this motor, its almost new (125,000 miles) I have read some others listings, but don't see anything quite the same as my problem. It just surges, pretty bad under normal driving. Thanks for any help, this is driving me nuts. Mark

Mine does the same thing? Just recently noticed it but it seems to be there at very light throttle all the time now.

Mine did the same thing, but it was up around 40-50mph, turned out to be a bad injector, replaced it and it was back to normal. I don't know if that is the same thing your talking about, but I thought I'd let you know so you can check.
