Mate! what an awsome set up! You must have had some fun making brackets and finding a crank pully to run the blower.
I always thought the VTEC honda engines used oil temp for the cold start cycle, but prehaps the H22 is differnt.
Is the idle temp air port as you called it a Vucume line? If so then the cold idle control solonoid is working but not getting any vacume to operate the throttle. Simple solution plumb it in to some vacum.
You dont happen to have any pics handy do you?
