Misfires can be caused by many things. A few common causes are problems with the ignition, fuel, or engine management systems. If the fuel pump and distributor are new, then they are likely not the source of the issue. A few things I would check are the ignition coil, ignition module, and spark plugs. If those all check out I would move on to looking at the engine management system. Similar symptoms can also be caused by a vacuum leak, either through a gasket or hose.
