sorry for the n00b question but i searched all the forums for a definitive answer but yielded no good info or pics.. short story is, bad gas mileage and the MAF sensor is my first stop. was going to log it to see what it's running but of coarse it just snowed like 8 inches here so a no go..

anyways, i know that i need to clean it with rubbing alcohol. shake it around in a ziploc baggy iirc?? but do i put the whole unit in there(illustrated) or can i take it apart more than this to clean the piece of metal. in my search i have read that you can also swab it with a Q-tip.. thanks in advance guys

Use electronics cleaner that leaves no residue. The aresol will work fine on the MAF filament.

i think its because i put it back in the car too soon, or maybe it was on its way out, my car was getting really bad miles per tank( 170)

all that stuff is OK, but what you really need to get the best clean is CRC MAF cleaner, i got my local o'reilly's to order me a case, it will make a huge difference in any high mileage MAF car.

ah, ok...I cleaned mine on a fri night after work and put it in sunday afternoon. I let it dry for over 24 hrs. maybe that helped?

ok, so the answer is yes, i can put the whole unit(pictured above) in the baggy with alcohol shake it around and then let it dry for more than 24 hours?

or do i just try to swab it with a Q-tip?

i just basically want to know if it's safe to put that whole piece in alcohol or not

i did mine in alcohol...

didnt let it dry 24 hours, but i used one of those air duster cans to dry it, and it worked well...

the answer is to goto the parts store and buy some CRC maf cleaner and follow the directions on the back.

well I am sure (not 100% sure) that you could just put hte whole thing in the rubbing alc. but I would let it dry out really good before putting it back in the car

yes, i put that whole piece in the rubbing alcohol...

you need to let the metal prongs on the back drie out before you hook it up and put any current to it

i bought electronics cleaner, sprayed mine put my air box back together re connected my battery and was fine

i would go electronics cleaner over alchy, but that is my .02

alcohol dries quick...we all know this...you know this.

if you want to be on the safe side...wait 20 minutes. after you do the ghetto baggy version.

the rest of us use CRC, i sprayed it...let it dry for maybe 5 minutes...then reinstalled it....closed everything up. took another 5 minutes. went for a drive and it was fine.

alcohol is fine...i think its a hit or miss kinda thing. i wouldn't be swabbing it with a QTIP though....no touchy...just dip it in the bag and wash it around. let dry...its prolly dry within 1-2 min. its alcohol.

yeah but the off the shelf rubbing alcohol has alot of water in it. i wouldnt do it that way, but thats just me. you cheap asses need to go spend 5 dollars on the right product, vs how expensive it costs to replace the maf if you were to energize it and there was still water in it for example.

I used CRC but I'm sure the baggie works fine too. I wouldn't use the qtip though, that sensor is sensitive.

Wow, I can't belive some of you are using alcohol to clean you MAF. Those things are pretty damn sensitive. Just spend the $4.50 and get the MAF cleaner or some electronic cleaner to be safe.

how often would you guys say it needs to be cleaned? What are the positive things that it does for your car once its cleaned or replaced, besides better MPG?

How hard is it to locate in the 2.8? 12v?

thanks.

haha, I used alcohol on mine and it worked like a charm. I read around and people said it was perfectly ok so I tried it out.

I also have an extra MAF though so I wasnt to worried about it...

soaking in 99% isopropyl alcohol and letting evap completely has always worked for me..
