Thankya thankya thankya...
Looks like the IAC is going to be the culprit... as corroborated by the man links you sent...
Most people on here have referred to it as the Idle Control Valve, or ICV which is probably why my searches for IAC didn't come up. But your searches for IDLE showed a lot...
I'm going to go disconnect my battery for 30 minutes to get a fresh restart (apparently needed after messing with the IAC) and then if the issue persists (expected) then I'll pick up an IAC, Part#8-17112-648-0 (for anyone's future reference)
