The idle air control valve is underneath the top plastic engine cover. It is on the top of the engine, near where the rubber tube connects to the throttle body, above the near side valve cover. Check for any vacuum leaks, by the way. Any air tube leaks or vacuum leaks can cause the idle to fluctuate.
