      No it does not move... is there a way to test the TB by putting 12v to one of the pins on it or something?

      I have changed the idle valve frequency to 200~hz and it still dies out on idle (dips to almost if not 0 rpm and then back up to 600), should I continue to raise the frequency? How high should I go?
