"I saw your post on the 986 Forum but did not want to make a post. There is a really easy way to test the MAF sensor with the Durametric tool.

Start with the car at idle

Select Motronic 7.2

Select Actual Values

Pick RKAT Bank 1 and RKAT Bank 2 from the list

These values should be right around 0.00 but no higher then .10 or lower then -0.10 If the values are in the -.30 or lower then it is likely a MAF problem. If it is higher than .30 then it is likely a vacuum leak. The RKAT values the amount of correction that is occurring to the air fuel mixture at idle. If your RKAT values are about zero your MAF is probably fine.

I just got this note from the folks at Durametric Software about me checking on my MAF. I went right out and followed their instructions and came up with these numbers:

Adaptation Range RKAT Bank 1 0.00

Adaptation Range RKAT Bank 2 0.38

These numbers would seem to indicate that the MAF is working fine, but there is likely a vacuum leak in my system. I am very impressed by the diagnostic power of this code reader and software package. It looks like it saved me swapping out MAF and such, highly recommended for Boxster owners that mess around with their cars.
