You have extra air leaking into the intake manifold that mimicks a throttle that is open further than it really is. Check for vacuum leaks.

sounds like your throttle positioning sensor is not set right so i would undo the two phillips heads that hold it and turn it till the idle doesnt fluctuate should be turned most of the way to the front of the truck. Also check your idle screw that throttle body could be set different.

Could be a dirty throttle body or low coolant, bad coolant sensor, throttle sensor, or idle speed motor
