djomlas,
keep your old MAF no matter what, unless you find out for sure it was bad. IF it turns out not to be bad you could probably sell it to somebody one one of the forums for almost what you paid for it since its brand new and people need them all the time. You could also try to sell your old one if it was still good for maybe $50 or something since it was used but still good.

i am not sure if i would even be able to return the one that i bought, IF it turns out that the old one is indeed OK. something like buying a wrong part...i dunno, i actually hope that the MAF is the problem, so that i dont have to investigate anymore and have a calm piece of mind.  even if it cost me $200 hehehe

from what I read the car can run briefly without the MAF and without incident.
I suppose you *could* try to disconnect the MAF and see if it runs without sputtering. If it runs fine minus the MAF, then armchair Porsche mechanic says it's a case of bad MAF.

it doesn't matter if you unplug the battery before unplugging the MAF. it only matters that the car is off when you do it. if the car ran worse when you disconnected the MAF, the MAF probably isn't the issue. when you unplug the MAF, the car loads a default fuel map that does a pretty good job of running the motor.
i believe those codes are lean threshold on bank one (running rich) and rich threshold on bank 2 (running lean). to me, this indicates a potential vacuum leak. my guess would be the oil separator bellows or the oil fill tube.

great news. when mine went bad, unplugging it cured the problem right away. didn't have to disconnect the battery. glad your car started running right after you reset the ECU.
