DeSnorkeling & MAF Problems?
I DeSnorkeled my Boxster about 8 months ago and it had been running fine. Just this past Friday 11/9/07 the CEL came on and my code reader shows P1128 & P1130 , both of which indicate a MAF problem. Has any one else had MAF problems due to DeSnorkeling? The air filter should be filtering regardless, whether the snorkel is on or off right? What is the expected life of a MAF sensor? My car is 7.5 years old with 39,095 miles on it.
Thanks

Desnorking shouldn't affect the MAF sensor. I would remove the sensor and clean in with electronics cleaner and reinstall. They can get a film on them or get slightly dirty causing a CEL. A lot of times you can clean them and get a quite a bit more mileage out of them.

My MAF needed replacement around the mileage you have. And that was before I de-snorkeled. Nothing too unusual to me. Evidently they're easy to replace yourself. And having a (non-dealership) shop do it for you isn't ridiculously expensive.

Thank you all
Thank you all for replying. I bot some cleaner and I will see if that works. I have heard that a new MAF costs about $400.
BTW, I also found that another cause of MAF malfunction and damage is from the oil separator bellows hose. Apparently this rubber hose will deteriorate from heat and oil and allow air to enter the intake system. It is a flexible hose that connects the separator to the engine and is located below the oil separator. It is most easily viewed and replaced from below when the car is on a lift. I'm going to check the integrity of this rubber hose too. Probably a good idea to inspected this hose at each oil change to head-off and potential actual MAF damage.

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
