N54 problems. Maybe HPFP?

[Templedakota]

Not sure what’s wrong with car guys. Can anyone help me look at these logs? I think maybe the HPFP but I’m not sure.
Any help is much appreciated. Car has no power. Will hardly get out of the neighborhood.

You need to upload the logs to Datazap, then embed them.

Reset all the codes and restart the engine and let it idle for 2-3 minutes and shut off the engine. Read the codes and let us know what they are for that 2-3 minutes period.

I’m thinking it’s a fuel injector. Bank 1 has index 12 injectors. Bank 2 has index 6 injectors. There is fuel on cylinder 5 and 6 spark plugs. Here are the codes after a couple mins.

Notice the huge difference in the AFR. It’s got to be the bank 2 injectors. Looks like bank 1 has been replaced with index 12 and bank 2 has older injectors.

At what point afterwards did the engine behave like this? Was it after you installed fuel injectors? If so, where the injector coded with the info stamped on each injectors itself.

No it was random one day on a cold start. Everything was running fine the day before.
