Surging at all speeds & temps

My 2002 F250 7.3 surges at all speeds & Temps. For example, when I get on the road & try to hold a steady speed it speeds up & down. Not big jumps in RPM but enough to make it awkward to drive. When I put the cruise on it smoothes right out? Is there a throttle positioning sensor or something like that, thats acting up? If there is, where is it?

Thanks for any & all help.

Best bet would be to scan it while driving, I have heard of the accel peddle causing issues like this, but I have never worked on one myself.

I am having kind of the same issue. my speed doesnt surge it is just the RPM's that jump a few hundred then goes right back to normal. CSI what is the best way to scan it while driving, AE?
