Has anyone tried to clean their MAF sensor with a cleaner like CFC MAF cleaner? Is it safe or do our cars just require a unit replacement?
Any feedback would be appreciated. Thanks.

I've used it on my M5. No adverse effect but no real improvement either. I think your MAF would have to be extremely dirty for you to detect an improvement.
Anything in particular making you think you have an MAF issue?

I tried it on my wifes SL500 with no luck. We were getting a CEL and the code was the MAF. I figured that for $6 and a little time I could try it. It didn't work so I ordered a new MAF from AutohauzAZ for a fraction of what the dealer wanted. Popped it in and within 3 cycles of the system no more CEL!
If only the CEL on the 993 would be as simple!
Cheers!

Well, I'm getting idle stability issues and it really feels like it's a dirty idle control valve or MAF just not getting the right air/fuel mixture. I clean my idle control valve regularly and it's always fixed the issue in the past. However, it's been needing its regular cleaning more often now, so I started thinking about other things that could affect driveability. When I got my clutch changed, my mechanic told me it might be my MAF going out as well.
Does anyone know where I can get a refurbished MAF unit?

If you find it is the MAF, I'd buy a new one rather than a refurbished one. You really can't refurbish a MAF without replacing the sensor. You might as well get a new one to start with. IMO.
Looking at what Pelican offers (see link), I see they include the housing with the sensor. You really just want the sensor that screws into the housing. Maybe you can get just the sensor at Sunset. I just replaced both MAFs on my M5.

Well guys, I cleaned out the MAF with CRC MAF cleaner and also cleaned the ISV once again today. Changed out the decklid shock while I was in there as well. Bolted everything back up and took a test drive. The car runs great. Let's see how long this lasts.

It's too late for pictures, but if you take out your airbox assembly (the entire thing, not just the lid), the MAF is directly upstream of it. Look inside the unit and the MAF sensor is right inside, you can't miss it. It's kinda hard to get to the screw that holds the MAF secure, so you'll need an extension, maybe 10" or so.

the actual part that may need cleaning is a thin metal piece in the middle of the big black tube.
If you have to replace a MAF, best price... at least for now...
is autohausaz

This is a Bosch part, same as Porsche sells.
Sunset price is $446...
