All you did was adjust the air mixture cable for temperature controls. Now apply the same principle to the heater valve (although I don't quite understand what you mean by "unscrew" as it's clip on in both instances). Make sure you temperature control is set all the way to cool. Unclip the cable off the heater valve by taking off the clip that holds the black catch sleeve and then take off the loop looking thing, off the valve. Turn the heater valve all the way shut, which in a 5th Gen Accords is counterclockwise, you should feel it click shut. Then slip the loop back on the valve, and clip the catch sleeve back on, taking care to make sure it is tight (no slack on the wire).
For 5th Gen Accords, the valve is located just below the intake plenum (near the firewall), so take off the plenum and access it that way. PS...this would also be a good opportunity to clean out your TB while you are at it.

Hey Hondatech, I sent you a PM, did you get it? I think I might have a dirty IAC valve just thinking about it. I want to say it happens under load (i.e., clutch depressed, brake depressed) but that wasn't the case at the stop light this morning as it still dipped down in RPMs. No clutch, no brake depressed.
