Engine sputters once after starting, then runs normally on 2003 Honda Civic

I start my car, it sounds fine, I drive for a few feet, and the engine sputters like it's running out of gas. After a few seconds, it starts running normally again, and continues running normally for the rest of the trip. It might happen more often on humid days? Not sure.

How many miles on it and what kind of spark plugs are in it?
127000 miles

spark plugs are Ngk Laser Dbl Plat/Spark Plug 6 months old

problem has been happening for at least a year, so that's not it.
EVEN though that's not your problem...Have you done a visual inspection of the plugs and cylinders? If you know what to look for (beyond the obvious) then it might tell you a little more about what's happening in those first few moments the car is running...sometimes more useful info than a scanner . T-belt's been changed of coarse? New tensioner too? fuel pressure after shut-down has been checked(for internal leak-down)?
I looked at the plugs when I took them out, but they seemed normal. Haven't done any of the other things.
EGR? EVAP purge soleniod ,(Brief light clicking)?

Try cleaning the throttle body and IAC valve or motor and see if that helps.
