Looping Idle after fuel leak HELP

[DMN]

Engine-SR20DET Blacktop(s13)
It all started after I had a bad fuel like leak for about 3 miles from the FPR hose, I have got everything fixed except that now my idle idles high and stays steady at 1.5k or 2k thenafter about 3 mintues when its warm it loops 1.5k up to 2k and back down continiously, drives fine, boosts fine( from the run up the street and back I took) the idle just loops up and down up and down. Now mind you it never did this before, WHat could it be?! Im trying to fix my car to bring up to college with me and I would love to get this issue resolved as soon as possible
thanks guys pleasde help me figure this out

sounds like there's a vacuum leak somewhere after the throttle body.

air is bypassing the throttle body raising the rpm. however the throttle is closed so the tps is telling the ecu it's idling. yet the ecu also see's the rpm is too high for idle so it shuts down the injectors to drop the idle back down...thus your bouncing rpms.

find and repair your vacuum leak.
