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.

I am looking at the service manual and it states to "release the electrical connector". Can I just remove the torx screw with the connector still on it?

I'd pull the connector first cause you dont want to have to grab the MAF on its longer side below the mounting plate cause you arent suppose to touch that, just pull the plug and then unscrew.
