I know it's been covered some time before, but a nice little reminder for those that haven't seen it- clean your MAF sensor- it's easy and cheap
The MAF is simply unplugged and then two phillips head screws (use a rather fine phillip head so you don't round the screws) and it's it out.
I use CRC MAF cleaner- $5 a can and specifically made to clean MAF's
Before and after pics of the MAF- first one it's black and kind of sooty looking, the second you can see the wires cleaned and the almost amber color of the "bulb". Simply give it several sprays from several different angles- let it dry good and put it back in.
This is a good time to throw a new filter in as well
You think this could be the reason why my idle with drop and come back when sitting still? I just bought the stock 18' STi with 32k miles. Dealership also ordered a stock OEM radio/backup camera before i would buy. Can anyone tell me what kind is this?
yeah, i used to clean my maf sensor constantly cuz i ran a K&N... i've since switched to a blitz sus filter, so i'll be good for a while. i've cleaned it with brake cleaner and with alcohol in a baggy... people say "brake cleaner is bad" so i tried the alcohol baggy, which left it wet far too long. im sure that stuff is similar to brake cleaner in that its quick drying.
and just so those reading this arent misled, that bulb in the photos is not the MAF sensor, it is the intake air temp sensor. the MAF sensor is inside the plastic tube and is very fragile... you should not spray it directly with the cleaner, which is why most prefer to shake it up in a plastic bag and try to clean it that way. i know some use a q-tip and gently wipe down the wires but i hear that is risky as well.
but thanks for letting me know a specific maf cleaner exists, for $5 i'd rather use that then brake cleaner.

I've used brake clean on hundreds of cars including my own. As long as it's non-cloranated (sp?), you shouldn't have a problem. And don't hold it 3" from the nozzle.

i have 70k on my 02. i've never cleaned the maf sensor before. always used oem suby air filter. about a week ago i cleaned the maf sensor and boy what difference it made! the car felt more responsive, especially the low end.
i just bought that MAF cleaner and cleaned my air hog, needless to say the air filter was DIRTY! and the maf sensor was covered in black sludge and soot, i was amazed at how much junk was there! ive already cleaned and re installed the MAF, just waiting for the filter to dry to re-install that to see how much better it runs now.. it never really felt like it was a step slower or anything, but i guess ill find out soon
So you guys recommend taking the MAF off of the air box, disconnecting the wire connector...and then placing it in a bag of MAF cleaner. Shake it around and then let the MAF dry?

Is there anything sensitive inside the black covering that shouldn't be wet? Drenching the whole thing is scaring me a little, but if everyone else is doing it with success...I guess I'll do it too.
