so you chop off the stud that holds it in the proper position on the throttle body?

No..

there are holes in the sensor where the screw go through...make those holes that the screw go through a little bigger..like this o(smaller hole) turns into a O(bigger hole) and that allows you to turn the sensor clockwise or counter clockwise

It doesn't take much movement to change the idle voltage.
