4.4 missing at cold startup

[michaelhinrichsen]

Hello, '01 4.4 with 99K slight miss at startup. It is somewhat sporadic and the engine may start and run fine for 2 seconds and then break into the miss for amout 2 to 5 seconds then be fine. All runs great otherwise once warm. It does this more at cold startup and also will do it less so when restarting when warm. It does not light the check engine light, but perhaps it will register miss fire? Any leads greatly appreciated.
