Looks like we may have a problem with one of the ignition modules. These modules are under the wiper cowl. We can swap them and clear the fault code a to see if they travel to the other bank. Another possibility is another coil causing the group to fail. Let me know.
Yes lets swap the modules first.
It could be a coil shutting down the complete bank since they are grouped to different modules. The cylinder order is 1-4 starting from the front on the passenger side and 5-8 starting from the front on the driver side. Label each coil and we will swap them. Swap 1 to 2, 3 to 4, 5 to 6 and 7 to 8. Clear the codes and see if the codes travel to the other cylinders.On a side note I have also seen the secondary timing chain tensioners fail causing the chains to jump. This can cause these ignition codes as well but this would only be the problem if the vehicle runs rough all the time.
