when driving on a level road, steady speed, under 1500 RPM's, i can sometimes get this really light engine surge going down the road. you can hardly feel it, but I know it's doing it. fuel filter done every 5k. what gives???

Mine does it, and others reported it also.

I assume that these trucks have a throttle position sensor. It is most likely that. My 01 v10 and my buddy's 01 cummins did, do, exactly the same thing. The ecu only gets a signal from it every so often. So if your running under a constant load for a couple of cycles, most likely all it will ever be, and a little breeze hits the truck and it takes slightly more throttle it will be a delayed response to the motor. It may not even require a change in load to show up. It's basically the same thing that your cruise control does when you up the hp.

Mine does a little surge too...particularly when I've slowed down and pulle into a parking lot...seems to surge from idel to 650 or so...then back down to idle. Never really concerned me other than just interesting that it does it.

Is there not a TSB on this.Something about a duty cycle motor failing or getting weak??

Mine does it too. And, the wind has nothing to do with it.
