I just went thru the above scenario, I could be wrong, but thats what fixed it for me. I did new plugs, pump and battery. All better now.
The problem is not a stumble on startup. The car just runs poorly for first 30sec. If you try to drive away too quick it chokes and coughs like an old carb setup in the cold. It will even occasionally stall. Only happens in the cold.
