This has been going on since my upgrade to 996TB 997T and 987 intake. Car runs so much better but can't shake this code. It always happens at idle. I can drive a hundred miles or so then codes. Thought maybe I need more fuel and I may need a higher pressure regulator cause of the larger TB but others that have done this mod have never complained. If I can rule out this Maf as good electronically I'd move on to other pastures.
