Cold acceleration stutter, any idea?

Whenever I start the car up for the first time in the day, it stutters if I dont press the gas more than 50% of the way down. It basically sounds like it's not gettin fuel (spark plugs/wires new), but once the engine warms it accelerates fine (usually only takes a few minutes). I was thinking maybe it was something with my injectors? Anyone know the answer?

could be a partially clogged injector/fuel filter or a cap/rotor problem.
