Swap all coils from bank 1 to bank 2 and see if it goes to bank 2? Coils can fry instantly. Hope its not a injector.
STFT 1 rised also a bit at 3831 revs.
Is it also coming back when you are running on less E content?

Im sure it is either plugs or coils, and if you ever need to swap injectors, remember that the seals are one time use only, and that you cannot swap injector positions without new seals. Check detailed instructions online.
