Default F.I.T Valve or Map Sensor?!?!?!?!

Got a eg w/ a b18b1. When i start the motor it idles rough for 5-6 sec then go to about 2.5-3k for another 5-6 sec then downs UP<DOWN>UP>Down. Took the fit valve out and clean it and tighten it all the way up still does it. So i disconnected the map sensor while it was doing it and it idle's fine. Car has no c.e.l and run awesome just has a werid start up. Once warmed up it idles fine.
