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.

i did disconnect it, and car ran worse.
BUT, i never did disonnect it, disonnect the battery and wait a min or two, and then turn the car over....so ill try that when i get home, couse im really curious

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.

well, did the test with unplugging the connector and then the battery like said, and what do you know runs fine, no hesitation,.
reversed it, and runs like ********************. so tomorrow i will be getting the new MAf and i hope its all fixed

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.

GREAT NEWS!
put the new MAF, reset the ECU, and the car feels better than ever.

i would like to say that i gained HP, but the fact of the matter is car probably got the power back hehe, love the feel, absolutely no hesitation when gas pedal is pushed, car responds great.

Hey DJ-
I got MAF in too. Only drove for a very short ride. The car did respond much better.
I've started a new thread - should i be worried. When I went to replace my MAF I noticed it. Can you take a look at that thread and tell what you think.
TIA
