92 Hatch w/SR20det bad idle

[snake240]

help guys! 92 hatch, sr20det, fmic, k&n airfilter, greddy type rs bov, 3 in down pipe, sohc ka maf, q45 ign chip,koyo rad, rest is stock.

just cleaned iacv. great improvement. while drivin around and coming to stops, only droppin to maybe 750rpm then back to 8, 850. very next day back to dropping 5 or 600 rpm. sometimes it will rise back up, other it stays and eventually gets lower and cuts off. also in morning it cranks idles high at 1200 then goes down to normal, or sometimes drops low.Ive tested 3 maf, all good. tps volt is good. did resistance test on iacv, bottom 2 wires in plug read 10.6 ohm, top 2 read 21.8. also no boost leaks.just redid grounds as well. also tried extra ecu bought off ebay year ago for earlier troubleshooting. runs super rich at idle. so took it back out. any help would be great! thanks
