ok so down on the backside of the IM there is a tiny little vacuum port. on the honda diagram the part number is B-23-10. I've got no idea where it goes, but seeing as it was a huge vacuum, i plugged it and it fixed my idle problem. my iacv cel is still on, but....
does anyone know where this intake vacuum port attaches to?
