93 Sunbird misfiring

My car has the 3.1L with 199,000 miles on it and 8 months ago or so it started misfiring, so i changed the plugs, didn't work... changed the wires, still didn't work... however, when i changed the plug wires... the first 30 to 60 seconds, it ran great and had it's old zip... then it started missing again... anybody have any clues what else it could be?
