Just watched your video. Are you revving it or is it doing it by itself ? It should have a constant idle on cold start up of around 1050 to 1100 rpm and then settle back down to around 850 to 900 rpm. As you have already changed the ISCV that must be ok, it seems like an air leak to me not electrical. Hope you get it sorted.
