so, tonight after another hour of driving and intermittent hesitation, i got home, popped hood and unplugged IAC. nothing happened. i revved it and it revved normal and returned to idle with ease and w/o issue... huh... its sitting w/ the battery disconnected for now... (hoping this might resolve a computer issue, or something, even if temporarily) still burning out on this one... need more humor/jokes/jeep drift vids...

peace

... open umbrella inside the house, use to break a mirror while walking under a ladder, call Jay Leno, give him a piece of your mind, click your heals 3 times while reciting "Chiddy Chiddy Bang Bang" backwards.

Lmao, I've just unplugged it, let it sit for 20 minutes, ground out the positive line, re-connect and have a nice day. There could be another way though, and I'm being serious on that.
