Not really, the fuels these days are that thin and full of additives that you shouldnt really need it. Try cleaning the maf sensor just in case? I know they can be a bit 'finiky' at times.
It's not going to be idle control as thats when your coming to a stop rather than accelerating. So as far as we know, ignition is ok, air is ok... just fuel really left to check.
On another note when was the last time the fuel filter was changed? Just thinking if its a little clogged up then on low demand it may not flow enough to supply correctly.
