It could be many things, unfortunately and without experiencing the problem first hand or being able to do some basic diagnostic tests its hard to say. Disconnect the small hose going to the EGR valve and drive the car see if the problem goes away. I have seen the EGR passage ways in the intake manifold plug up causing all the EGR to be directed into one or two cylinders causing those cylinders to misfire on part throttle acceleration. It could have an ignition problem, bad wires or plugs but I would look at the disconnecting the EGR first if the problem goes away you have found the area the problem. Any repair shop that specializes in Honda/Acura will have seen this problem before.
