Idle problem

I balanced my throttlebody a few days ago and now i have an idle problem,.. when i did the 15 min adaption the idle went up to 2000ish rpm a few sec and then stabilized at 14-1500 rpm.
But when i drive it stops at 2200 when shifting and when coming up at crossings and stops it goes down to 2200 for about 10 sec and then backs down to 1500, and so it goes on at every stop..
If i lower the idle by a throttlestop will the idle speed always be low or is it controlled by software?
