i have a 1993 ex with a b16a3 no codes it drives fine but when i get to a stop light it idles 1200-1600
 
you might have a vaccum leak or the iacv or fast idle valve or an air leak in the TB or the IM itself check the fast idle open the cap up screw it down so air dont leak and check. not sure about anything else cuz am having the same problem but am gettin a code 3 al the time hope this helps :)
