    Default IAC Issue

    I'm leaning to a bad IAC, after playing with someone else's install. I started back with on page 1 from scratch. I think the IAC intermittently works. I set idle with blocked then adjusted secondary. I had a nice idle and IAC at 5% and got it all working on Friday. Monday idled like a turd again. Also noticed the Hold & Decay while not changing settings would behave differently. Today got back to it, if I block or unplug the IAC makes no difference. Does this all sound logical?
