there are a huge list of things that cause bad idle
besides a simple sticking isc
gross misfiring, over 50 reasons or bogging, like low fuel pressure.
its a daunting process to find it.
what i do is add air to see if the ISC is failing , if added air , cures it and engine run ok, then it not misfiring doing it.
on the G16b that is not easy, i can only open the TV valve a tiny bit by hand say and see if added metered air help it.
