Reported cause
In one case the problem proved to be a leaking oil filler tube cap.
Leading evidence: 'leaking oil filler tube cap' (1 discussions report identifying this cause; no attributable repair resolution). Across 1 matching discussions, the most frequently mentioned possible cause is 'leaking oil filler tube cap' (1 discussions; 1 report identifying it and 0 suggest it). The most frequently discussed action is 'Clean boxster maf' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

At one or two other times I cleaned the Boxster MAF.

Suspected cause
The other time I can't recall if I actually cleaned the MAF, but the MAF proved to be bad.
Clean maf do a re-calibration of the car's e-gas system

Also, I dare say you'll get more bang for the buck, so to speak, of instead of cleaning the MAF do a re-calibration of the car's E-Gas system.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

My question is.... Have any of you guys actually cleaned your MAF sensor as a PM move, even though you have had nothing wrong with the engine? ie:- no CEL showing or lack of power , no fault codes coming up. Kind of as a Preventative Maintenance move on your part. Just wondered if it was a good/bad idea.
nope. Id say it is fine until you get a code. You can monitor it was an OBDII scanner and tracking the voltage. I doubt you would hurt if you made sure to use MAF cleaner. I dont really see the point tho.
I clean mine every so often (after all, I'm a "boy racer" (in Hurdigurdiman parlance
) with delusions of grandeur, so I have an aftermarket intake system with an oiled filter).
Anecdotally, cleaning the MAF can help if you've noticed fuel economy getting worse.
There is no need to even as PM clean the MAF. With a stock and properly functioning air filter system the MAF does not get dirty. (It is a thin film MAF and one benefit of this design is it is quite a bit less sensitive to any dust contamination. The working area is huge compared to the older hot wire style MAF.)
Now I admit I have in an attempt to get to the bottom of a symptom cleaned the MAF in my Boxster, the first time at around 80K miles. There was no dirt. The engine did seem to perk up some afterwards, but this was due to the variability of the failure of the real source of symptoms: the AOS. It perked up when I added some Techron to the fuel tank. But later as the AOS got worse nothing perked up the engine but a new AOS.
At one or two other times I cleaned the Boxster MAF. It wasn't dirty and I cleaned it over white paper towels to catch any dirt. In one case the problem proved to be a leaking oil filler tube cap. The other time I can't recall if I actually cleaned the MAF, but the MAF proved to be bad.
I've never bothered to clean the MAF in the Turbo and the MAF has been ins service now for just over 125K miles.
My concern with cleaning the MAF as preventative maintenance is it subjects the MAF/wiring harness connector to unnecessary wear and tear for as time goes by these and their wires get more fragile due to exposure and there is the risk of insulation or even wiring fracture or pin/connector damage.
Additionally there is the risk of static discharge into the MAF or the wiring harness, the latter which leads directly to the DME.
Last but not least drop the MAF just one time�
You want to preserve the MAF? Help it have a long and healthy life? Keep the stock air filtration system and change the filter at reasonable intervals. And keep your hands off the MAF.
Also, I dare say you'll get more bang for the buck, so to speak, of instead of cleaning the MAF do a re-calibration of the car's E-Gas system. No need to do this that often, at every oil change would be a good time or at the start of the driving season for lightly used vehicles. Do it after you have driven the car some not right out of the cold garage and in the light of the first nice spring day.
Why are you even asking this question, let alone on this forum with so many worry warts and clueless peeps that just like to throw parts on for the hell of it?
My question was a good one. Answers seem square and fair and say 'leave things alone'. That was my thought, but I asked the question simply to confirm my initial thought of 'don't interfere if a thing is running good'. Leave well alone. I change the dry air filter often Macster and don't have the 'e' gas but the cable gas pedal. Well.... I think I have lol. Hey thanks guys.
