Conflicting 2B22 Code: Misfire or Throttle Body Issue?

Start by inspecting the throttle body actuator on bank 2 for any signs of damage or malfunction, as the 2B22 code suggests. Clean the throttle body to ensure it's not sticking due to carbon buildup. If the issue persists, consider checking the high-pressure fuel pump and fuel injectors for proper operation, as they can also cause misfires and jerking. Let us know how it goes or if you have further questions!
Thank you, I will give that a whirl first. It is strange because also it gives the freezeframe for the high pressure fuel pumps, the bank 1 hpfp reading 0. I guess it is a glitch in the app. The information given is completely (I assume) unrelated to the code given. Wrong bank even. Do you think that the bank 1 hpfp is actually at 0 pressure?

It's possible that the reading of 0 pressure on bank 1 could indicate an issue with the high-pressure fuel pump or a sensor malfunction. To verify, you can manually check the fuel pressure using a mechanical gauge to ensure accurate readings. If the pressure is indeed at 0, it could be a sign of a failing pump or a blockage in the fuel line. Addressing this promptly is important, as it can affect engine performance and safety.
