08 boxster...after a hand full of repairs including AOS and throttle body cleaning my car had sluggish delayed acceleration and would stall while idling. I pulled the tube that houses the MAF and found some oil droplets in the screen and evidence of oil on the MAF (not on the wire sensor) but in and around it. I also noticed a puddle of oil downstream of the MAF in the air box tube ....would this be the cause of my problem. Should I give the tube a good cleaning and spray the MAF w/Maf cleaner and see if that works. Thanks V

Oil should not be on the MAF, the line from the AOS is downstream from the sensor, so it should not be able to get anything on it.  Most common source of oiled MAF sensors is overly oiled aftermarket air filters.

Cannot see how, the MAF is between the air filter and the throttle body, the connection for the AOS is between the throttle body and the intake system.  If it came from the AOS, it should be in the throttle body as well.

Yes it was full of oil. I cleaned the plenums all the way to the flex tube going into the MAF. I only recently removed the MAF tube to find oil in the bottom of the air box. Ill clean it out and spray the maf with cleaner see if it helps. V

Cleaned out bottom of the air box, MAF and MAF tube.....no more stalling and delayed acceleration. Was an easy fix except for the 5 point security screws for the MAF.....what are they thinking.

Ok, so I found a fairly thick o ring left over after reassembling the MAF tube. I assumed it went between the MAF tube and air box but now it 

seems very tight for the 2 spring clips to snap in place didn't want to force them. Am I seating it incorrectly ?
