"everything seemed good and at 50 miles it throws the bank 1 and bank 2 SAI codes again
Obviously this is not the regular SAI problems.
Now that you've become an involuntary expert on the subject- the SAI system should not be running 50 miles after a start. So what happened then to produce code? A bump+loose connection? Fault to ground ? Such a transient fault would set a Pending Code and the next bump would add to the store of Pending codes and eventually the CEL would illuminate on the dash.
I ask this seemingly silly question because you've tested the system physically and electrically very carefully many times.
After the car has warmed up, can you wiggle any of the harness/connectors to produce the CEL ? Unless we can reproduce the situation that prompts the CEl we're just flailing.
The other more intelligent(?) option is to check continuously for Pending Codes whenever you are driving. Maybe there was a Pending SAI code set at start up but it requires reconfirmation before the light on the dash illuminates(at 50 miles) ? Or could this be just a Drive Cycle readiness process and it will eventually become 'ready'.
Good luck !
