You are definately out of the woods until you are back in the woods.

Sorry, couldn't resist. I've never seen any discussion or reports on how long a clean MAF lasts relative to a new MAF. You are officially the guinea pig. In theory there's nothing to wear out, so I would expect a reasonably long life.

Even if the MAF does go south it's not that big a deal. The ECU has a mode which ignores the MAF signal and guesses at the fuel injector pulse width. The car doesn't run great, but it runs, so it's not as if you can get stranded.

BTW, the car is drive-by-wire. The M104s since 1993 have been. The throttle cable is for limp mode.
