So what’s this I hear about reinitializing the computer after changing a mass airflow sensor? My sensor is shot (i.e. the filament is visibly broken) and I am going to replace it with a rebuilt unit ($305 btw….is that a good price?). The parts guy said something to the effect that the computer has leaned new values (its supposed to be 1?) and it needs to be reset?

Is it true?
Is it necessary?
Is this something I can do myself?
