Help diagnosing codes

[fs34]

I posted in the general forum but haven’t had any replies, maybe someone in here can help.

The car went into limp mode and I pulled the codes.

So far I have

-checked spark plugs, look good
-moved coils, problem didn’t follow coils
-swapped fuel injectors, codes stayed with cylinders 6&7
-swapped cam position sensors

Still get the following codes read from protools:

2758 ignition, cylinder 6 activation
2796 no description found
2B57 no description found
2759 ignition, cylinder 7 activation

I am at a loss here. Anyone have any ideas? I had the car towed to the dealer for a diagnostic, should have that done tomorrow.

2796 = throttle body actuator fault
2b57 = emergency mode activated

Would the problems at cyl 6 and 7 be caused by the throttle body actuator of the respective bank?

I didn’t realize 2796 was a TBA specific code. I hope that’s all that it is. The car is at the dealer waiting on a diagnostic scan. Hopefully that’s it’s and I can get one to install myself and be on my way.

The symptoms line up actually, the car was fine after going into limp mode but now it’s persistent. I would have expected more codes associated with bank 2 though.

i have heard of a few valve springs breaking and will cause similar faults, just an idea
