I swapped on a d16y8 IM onto my d16a6... all the vacuum lines are in the correct places and one is plugged, because i am not using a dashpot. Anyways, my idle is @ about 2,000 when i start, and will drop to about 1500-1750 in about 3 minutes sitting...but when i drive it, i get no CEL and my idle will bounce sometimes even as fast as 1,000 rpm jump every 2-3 seconds. I dont understand the problem, because i dont think it has air injection becuase its not 99-00. All nuts are on, even the dumb one in the middle/bottom with brand new Hondata Gasket. The idle adjustment screw is all the way closed leading me to think vacuum leak, but i have yet to find one. Any help would be appriciated, new TPS and MAP were put on and my connectors for the two are not switched...thanks
