had a few minutes to play with the car today and if i take and press the linkage back all the way so the blade inside is shut and it idles perfect then ? i really need some input on what to do. i think a stock throttle body is really gonna hurt the car. i don't mind a little bit of a high idle but it's idling way too high right now. base screw is almost all they down as far as it will go. i just don't know enough about this stuff to know where to go from here.
