Get new airflow figures with the MAF at the same rpm as in your early posts to compare.
If they're the same or similar, I can't see how the original MAF sensor would be faulty.

The new MAF is reporting higher air mass , so I guess the ECM-134f "signal to low" meant the ECM did not detect enough air flow through the MAF.
The TCM-OA31 fault also went with the new MAF fitted.
The car is running great probably due to cleaning the Intake and throttle body .
Thank you to all for the help .
