Is it possible your cold coolant temp compensation (both low temp AF and % 
added in cold PE/AE? and by TPS%) is too much and the plugs are loading up? 
Then restart with the engine "warmed up" helped? Or maybe what Bruce said ;-) 
I know my GN is like that. Warmed up ran like a champ. I played for awhile 
before I got cold driveability right, and now it runs better than any program 
I ever had ;-)
