Idle drop by 500 rpm?

I would close off the secondaries first, all these other cats are pitchin a damned fit about it.
Thanks Brother Rob, I just Caint wrap my head around the fact that, after Y'alls instructions, even Cold, she Idled At 650, then 450 in Gear.... I brought everything back to baseline after the stalling in gear issue. Now, it's A Monsoon out there...
