0103 is MAF HIGH freq; it's not wiring (it shouldn't be)... If you have a SD tune this is normal to be set. If not, well, the code means the car is running in SD.

Give your guy a fair chance to make good. I SUPPOSE it's possible that a MAF fails and puts out some high freq, but I've never seen or heard of it. Borrowing a buddy's MAF could rune that out. The code definitely means that the car is in SD though whether intentional or not. Maybe the MAF fail freq was inadvertently set low.

More than likely you can find the problem quickly with scanning the sensors.It's eaither a bad part somewhere or the tune. I'd go with bad part.
