    The ECU is learning the MAF sensors, TB position sensor, etc, etc. It will clear out in a few hours (definately less than a day). I would drive around on all kinds of roads, just remembering to have to give it some gas at the stop lights so I wouldn't stall. Often I would through it in N, so I could give it a little gas. Don't worry, from experience, it clears out and will be idling normally in a short period of time.

    But it can just be incidentally the Idle Air COntrol Valve :)
