UPDATE!!!

Drove the car a few hours and cleaned the TB, now the car idles perfectly at 650rpm. Is the reprogram still needed to be on the safe side? Thanks again, Chris. :renntech:

The MAF is not used for idle measurements.

The "125" MAF is a different design so I think you need the reprogram so it properly measures the air flow. Porsche would not have their dealers do if they didn't think it was needed.

Loren: I found a MAF in a box of parts that I received sometime back. I have no idea where it came from and I have no idea if it will work, but thepart number is the correct one for the 99 996. Is there a way test it without installing it? I was wondering that if I installed it to see if it works and it was defective....would it create any unnecessary or troublseome problems with the DME.?

The only way I know to test one is to put it on the car and measure the air flow with a PST2 or the Durametric Software.

Thanks Loren for the clarification. This site is a life saver!
