On a cold start, the idle is way to high, I have to put it in drive right away to lower it down a little. I heard something about the (IAC), if so is there a way to test it, or is it something else, fuel injection, if it were a carb I would just adjust a screw.

If I left it in park the idle will go to normal in a minute or so, but its just to high at a cold start.
