It helps to clean the pintle and the IAC bore where the pintle moves into/out of.
And yes that is the port you block off. The outer port is the bypass air and the IAC controls how much of that air bypasses and controls idle.
So yes clean the pintle and bore. However, I would still block off the IAC port physically and see what happens w the idle.
