first off, remove the throttle blade and then mark the shaft where it is even with the wall of the throttle body, then remove the shaft and cut only the outer half (on both sides ) of the shaft. then reinstall shaft and check to make sure it is flush. then reinstall the blade & new screws, then trim down the screws. thats a pretty rough overview.

is there a link on how to do it step by step?

and so you dont touch the back of the throttle shaft at all, mine has been grinded down in the areas around and between the blade screws, the front and the rear of the throttle shaft
