Now I did notice that the large vaccum line coming from under the IAC has a lot of suction. Is this vacuum hose leaking -
Unplug the valve if it's operating properly the engine will shut off. If there are vacuum leaks it will stay running and you can listen, find and fix them. A lot of the time if the idle seems high when you start, hit it with a hammer, if the idle drops the valve is sticking, probably has a cracked piston in the valve and needs to be replaced.
