One thing comes to mind with your car. There is a bulletin to solve a problem with fuel injector primary circuit codes. P0351-P0356. This may or may not repair the misfire, but it will prevent the false codes. If this is your problem, all 6 coil packs need to be replaced. Then the PCM will need to be tested. Only a Ford scan tool can do this. If it fails, the PCM will need replaced and reprogramed. If this is not the case, and you would like to get your car’s misfiring problem diagnosed, I would recommend having a certified mechanic come to you to service your car.
