The IAC is the idle air controller. It's a small, cylinder shaped motor that regulates idle speed. On your 740, it should be silver in color and it is located under the intake manifold. You'll notice two rubber hoses on it. There's also a harness plug on the front of it. See the FAQ for cleaning procedures. It's really an easy job. You'll need a can of spray carb cleaner. After I cleaned the one on my 740, it has yet to stall.

Good luck with it.
