changing the MAF
I justed received CEL 1128 and went to clean the MAF. I have located it but have a question on removing the wire plug.
Does it just pull out or does it have a clip that has to be pushed out?
To be more specific..... the wires( I believe 4) are in a rubber connector that is oval that goes into another connector. Does the oval come out or both? I do not want to start pulling on them until something snaps.
Thanks

MAF is held in by Tamper Proof Torx screws.
BTW desnorkeling your intake does NOT damage your MAF. MAF's break and are finiky too, sometimes you'll get one that lasts years and years and you might get one that breaks several months after installing it.

I'm complete novice when it comes to DIY and the Porsche. Any photos of cleaning MAFs?

BAM! http://mike.focke.googlepages.com/checkenginelightcausedbymassairflowsensor
scroll to the bottom of the link and you'll see some photos of its location and the screws and tools you wil need. Just grench that MAF in MAS AIR FLOW cleaner spray and let it air dry and DO NOT blow on to it, that will create a fog on it.
Just shake it around to let out any puddles of the cleaner stuck in the sensor and let it air dry for for 5 minutes then reinstall.

How is your car running?
I had both of those codes (not de-snorkeled) which may or may not mean the MAF is bad, the only way to know for sure is to have it hooked up and tested at your dealer or other shop that has the right hardware to check.
I have replaced the MAF, AOS, and cleaned my throttle body. Codes have not reappeared, however, I have found a vacuum leak in one of the rubber sleeves beyond the throttle body which is causing a rough idle and code P0507. Vacuum leaks are common and the cause of many issues related to the normal running of our cars, you may want to have the MAF tested before investing in something that may not be bad.

Coonster - The wires connect to a wiring harness that disconnects from the MAF. The MAF itself is removed by unscrewing the the two Torx T-20 screws. These are tamper proof screws and I believe you need a anti-tamper bit. The center of the bit has a dimple that allows it to be fully seated into the screw.
Good Luck!

Maybe I'm just silly, but how do you know if you have an E-gas version? I have an 01 S just like your's. Thx, Jon

They changed over to e-gas with the 2000 model year. So yours has e-gas.

You can also check the part number on your stock MAF. Each of the two bosch parts explains what part number it's replacing.
