bump... im actually out of town now for the holidays but i will give this a shot when i get home.. i know that the evap purge is wired in the car right now..
so basically your saying try taking out the charcoal canister that is on the firewall and plug up which lines??

whats the afr's at when you start your car when its cold?im running the aem ecu and we get pretty cold over here,as low as -50 brrrr.my car had the same problem.richen it up a little in the iat table or cold start tables if hondata has this option 
.when you start your car it likes to be pig rich (like 10.5) until it hits the desired coolant temp.and how much timing you running during inital cranking?

i wish i knew, although my car was tuned during this type of weather, it ran just fine a year ago.. i have no idea regarding timing.. i'll give a try to cleaning air control valve.. hope it helps
