2011 3.0 v6 injector faults

Hi all,
After advice with a fault I have, after the car has been sitting alot the last few months driven maybe once every 2 weeks, I had a performance restriction pop up on the dash but thought it may be a battery issue given it hadn't been used. I read the code and it came up with the following;
P1204-injector 4 open circuit or ground short fault.
I then cleared the fault code thinking that it was a low battery issue after standing for so long, went for a drive and then had the following code come up;
P1206-injector 6 open circuit or ground short fault.
I then cleared the fault code to drive it home and got the following fault code;
P062E(pd)-fuel injector driver circuit performance bank 2.
The performance other than when it restricts it seems fine tbh, went out the night before to give it a run to make sure it was ok and it drove well.
Any ideas?, is it worth/easy to remove the harness and check resistances? Or had this happened to anyone and it's an other fault

It is worth checking the resistance and the loom yes.
Follow the injector loom all the way back to the engine ecu as well just to make sure that there is no damage.

Don’t suppose you know which are injectors 4 and 6? Are they the rear two on the passenger side?

Good question...
Drivers side front to rear of the engine,

Passenger side front to rear of the engine

The old way was.
