Default 90 accord idle is high like 3k rpm's how do i fix this?

My Honda use to do the famous Honda idle. Now it just idles high and does not go back down. It sits at 3,000 rpms and does not idle down at all. How can i fix this?

not sure if this will fix it but my 90 accord used to do a surging idle thing like rev up and down by itself at idle. w/ the engine off, on the front rightside of your intake manifold is a sensor w/ 2 screws on the top of the cover. unscrew it and mind you these screws may be hella tight so wd40 and careful not to strip the screw heads and there's this white circular plastic thing. screw that all the way down somehow w/ ur fingers if can, if not use a flathead screwdriver then screw back the cover n restart engine n chk idle. hopefully this fixes it, all the best

Check your vacuum lines and consider you might have a bad intake gasket. If your intake gasket goes, it can cause these issues.
