When my plenum gasket was bad, my cruise control would surge when I was going down a hill and the rpm's would jump back and forth. I'd check the plenum for oil, and also all the vacuum lines going to the intake manifold.

The reason I was asking about rpm's, was because my truck at 70 MPH (which is somewhere around 110 KMH), is at 2200 rpm's with 33" tires and 4.10 gears.
