Dude, I cleaned my MAF !

[NickCats]

Thanks for the info, Griz !

djomlas, does you car run any worse with the CEL on ?

I have noticed the car runs a lot better since I cleaned the MAF, but it may just be a placebo effect...

AUDIOGUY - I did take a look at the air filter while I was in there. I had it replaced last year at 30k ( car has 42k now ) and it looked pretty good !

Question - when you get a CEL, I thought it would stay on until you got it reset ( or unhooked the battery ) ?

who has a DIY for replacing the MAF? I've got 40K on the clock now and the idle doesnt sound as smooth as it a year ago.

p.s.
Mike Focke's site says to spray the MAF cleaner into the "hole with the wires". Can anyone elaborate on that point? I don't want to spray the wrong part on maintenance and end up spending $250 to buy a whole new MAF.

once you take it out you can see what htes talkinga bout.
BUT, i sprayed the whole thing, all the wires, you cant harm anything.

and as for taking it out, well...once you get to the engine, its right there, just unbolt 2 screws, pull it out and clean it.

but on renntech poeple had bad experience just taking it out and cleaning it, as it seems that the MAF doesnt like to be taken out or moved around, so they end up getting CEL even though they didnt have one before. just a tought.
i cleaned mine couse of the CEL, and it was already out for the EVO intake...

Hi,

A dirty MAF is only one possibility. The other is that the MAF has failed (which also is the case in a high % of these CELs).

If dirty, a thorough cleaning (read THOROUGH) can loosen the dirt/oil accumulations and everything will work as new. It's generally a good idea to do several sprays with the Cleaner, as each successive spraying removes some more of the dirt from the Hot Film. If you just spray it once, or not thoroughly, the solvent will flash-off and redeposit the dirt/oil in it's place, the idea is to flush the bad stuff away.

Many who have attempted to clean the MAF and were unsuccessful I suspect either had a Failed MAF (in which case cleaning won't do a thing), or didn't thoroughly clean it.

You can hook a multimeter to it and see what readings you get. There is a specific voltage range for a MAF which is still serviceable. If outside this range, replace the MAF. Hope this helps...

Happy Motoring!... Jim'99

do you know what the readings are sopposed to be?

Would it be a good idea to clean the MAF even without any CEL..?
