2000 Porsche Boxster

Engine Performance problem
2000 Porsche Boxster 6 cyl Two Wheel Drive Manual 41000 miles

The car comes up with a trouble code of P1502. When I disconnect the Air Mass meter, it runs great. So I replaced it with a new one, same thing it only revs to about 2000 RPM's, when I disconnect the meter it runs great. If I leave the meter connected and erase the fault code it again runs great until I restart the car. It sounds like the computer needs to be reset?
