i got the same prob in my car but i dont think its ur map sensor. take off ur intake and inside the throttle body there should be a lil hole while ur car is runnin stick ur finger over that lil hole if it dies back down to stock idol then its ur lil thingy on the back of ur intake manifold. cant really tell u what the thingy is cuase i can remember i jus know what it look like. if its not that then spray some like carb cleaner right where ur injectors are. if it gets sucked in then ur car will act a lil funny real quick then be fine. but if that happens find out which injector it was and replaces its lil o ring seal thing. if those 2 things are fine then beat it with a honda tool til it works right.
