As Carl says, check the cold start injector - they sometimes leak. Remove it when the engine is hot, see if it dribbles. Have you cleaned out your idle control valve (by the thermostat housing)? If not, remove it, empty half a can of carb cleaner into it, followed by a generous amount of WD40. You will see lots and lots of soot coming out. Have you cleaned out the throttle body + butterfly? Again, lots of carb cleaner followed by a bit of oil. -- Grunff
