About 50% of the time when the truck is cold, the engine will stumble for a second or two at startup. It then jumps right up to fast idle at about 1500 rpm. It never stalls and only does it about 1/2 of the time. Any ideas of what's causing this? I did a full tune up a month or so ago and it still does it. It runs great otherwise.
EDIT: When it's warm it starts up fine.
