I just bought a 2000 Porsche Carrera. After the first day in my possession the check engine light came on steady while driving. I took it to a factory trained tech in a Porsche dealership and he diagnosed it to be from the fuel/air mixture. The Porsche tech took forever to determine that the check engine light was supposedly being caused by a bad mass air flow sensor. So, $1100 later I got my car back from the shop with a new mass air flow sensor. The next day home, after driving it for 50 miles, the check engine light came back on steady again with no noticeable change in performance, just like before. What on earth could be causing this? I'm starting to think that the previous owner got rid of this car because of this recurring problem that maybe no one could fix. The car has only 58,000 miles from one previous owner. I got the car thru an auction so I don't have access to the previous owner or any of the car's maintenance records.
