Re: Hard to start after fuel up
Yes there is a charcoal canister, the pupose of which is to absorb fuel vapor (evap) so it can be drawn into the manifold later and burned. There are some valves that control the fuel vapor going into the canister from the fuel tank. One you may want to look at is the Onboard Refueling Vapor Recovery (ORVR) which is present on 99-00 civics. It's valve opens when refueling. You may be getting liquid into the canister somehow? Maybe the turbo is overwhelming the evap valves and drawing fuel through the system. Try not filling up all the way and see if symptoms persist. PM me for more detailed info.
