i have a 92 civic si with a 95 gsr swap...the engine is totally rebuilt for boost except the camshafts...when i pull up to a stop light or stop sign and put my car in neutral it idles really low and fluxuates sometimes so bad it stalls...i was wondering what could be causing this to happen...thank you

Well theres always the 2 basics. Air and fuel. Check if your throwing any codes from the ECU. I would then trail threw the ignition system and see if anything is loose. Maybe your distrubtor cap is toast. Also pull the hotwires 1 at a time to see if every piston is getting spark. Make sure your timing is good and your spark plug gaps are correct. Remember its just a game of air and fuel.

IACV could also be a problem....have you ever cleaned it???

I have a similar problem as well.
I have a Y8 with stock ECU.
new cap, new rotor, new plugs, new fuel filter.
