so i put my stock intake back on (because im puting everything back to stock in order to sell the car), and now the car idles at 2000 rpm's. i first start the car and its at about 1700 rpm, but once you give it gas and come to a stop again, its stuck at 2000. i still have the header and catback on if that may be doing something, i have no clue. it's a 94 accord ex 5spd by the way. if anyone could help me out i would appreciate it. thanks

 

reset your IACV back to normal idle... search it on this forum, it deals with taking off your IACV and turn on the car.. mess with the idle screw and then turn car off.. take out Hazard fuse for 10-15 seconds, put back in.. start car back up to have it idling normal again.
