well could mean your iacv needs cleaning or is bad but sounds to me there seems to be something wrong with either fuel pressure( too much air not enough fuel.... kinda seems like a vaccum leak as well maybe the fpr? not completely sure but it probaly has something to due with the a/f ratio....

well id get a multi meter best investment if you do your own work in a car....test the resistance of the map sensor first since that controls the signal for the a/f ratio along with the tps...then id check the injectors make sure that they have the correct reisistance.....and then if that all checks out id go ahead and check out your fuel pressure regulater and its vaccum line because i dont think that vaccum hose would affect idle but yea id just check that out....

and if all that checks out well.....then id wonder if your running the correct ecu and wiring harness..... but yea im sure you are since it runs and idles fine.....so yea i guess check that stuff first.
