Have th ebattery checked for condition and load test then have alocal pro look at this due to the misfires are very hard to figure out where the problem lies. Those are the 300 series codes and a lot of those may disappear once the misfires are fixed.

Thank you all
In fact that connector of the harness to the gear box was completely broken.
Finally after 2 years of research we found the problem.
Great thanks for all those helped me :)
