At cold start, 4-5 hours sitting there my car will start up and rev to 2k and spike down to 1200 then spike up to 2k and so forth until put into gear. car drives normal and after warmed up will start like normal. help?

only on startup and randomly. it will start up like normal or start up revving on its own. no never stalled. RPMs never drop below 1000. unplugged my iacv and it will do the same thing. revv high. plugged it back in and ran normal. i plan on cleaning out the throttle body with my cam seal change. and see if that works.also remove and clean the iacv.
