A miss fire could be several things. Faulty spark plug or wire, Faulty coil (pack), Faulty oxygen sensor(s), Faulty fuel injector, Burned exhaust valve, Faulty catalytic converter(s),, Poor compression, Defective computer, But you have done several of these parts already, I would check the fuel pump pressure and do a compression check, change the plugs and wires...
