2008 N54 335i. Any tips on what this might be? Codes changed from cyl 1&2 misfire to throttle after resetting throttle adaptations.

I turned on single bank fueling and 3 port boost solenoid not sure if that has anything to do with it. Can you even read afr on mhd?

Did you wait 30 sec after resetting throttle?

Throttle: after reset, turn ignition off and then back on, wait for 30 seconds before starting the engine!

yep throttle code is gone again and back to 1 and 2. fuel bracket bolt at 1 and 2 was loose so i torqued it thinking that would solve the issue and it still didn’t
