Look in the FAQ for the throttle hang fix, which is essentially the moose fix. The IAC is the sort of bright silver can with an electrical connector on the end poking out of the upper intake manifold near the firewall. (About 5" left of the brake fluid resevoir) It's just behind the sliver hat-looking thing with the little green hose hooked to it. They cost about $70 to replace, but cleaning and fising the moose problem is pretty easy. The moose usually shows up as the weather cools down.
