Use the MAF cleaner. I used the parts cleaner from Radio Shack on mine and it leaves a thin film that will keep the maf from working right.

I've never had that problem. But I always apply the cleaner to a Q-tip, then wipe the wires clean, then hit them again with a dry Q-tip. I've never tried just spraying the wires down. Maybe that's why you had an issue?

Does doing this actually help? I have 128k on mine and I don't think it's ever been done :confused:

The Cleaner Really Does A Bang Up Job, If U Still Have The Screen On, U Will Be Amazed How Dirty It Is.

At work, we use glass cleaner (windex works best) and use an air hose to blow it dry. Make sure there is no moisture on the diode, because it can blow the diode up. Seen it happen to a buddy of mine. I use the glass cleaner and a q-tip, then use air to get it dry. You will notice a diff on most cars depending on how dirty it is.

have a good one.

Best idea is to use the specialized CRC MAF Cleaner as mentioned above. You just spray the living snot out of the wires, inside of MAF. No need for q-tips at all (saves from possible damage due to contact). Just spray on and it will evaporate/dry fully on it's own and will not leave a film. I use it once/yr on my T/A - never noticed any difference in how the car runs - but it can't hurt...

Are you sure that stuff is any different than electronic parts cleaner? It just seems like it could be relabeled.

Below is directly off can. It may or may not be the same as electronic parts cleaner - but why not just buy the stuff that states that it is solely for the purpose of cleaning MAF's? Priceis the same...

'CRC Mass Air Flow Sensor Cleaner
Evaporates is seconds!
Use every time you clean or chnage your air filter

Safely cleans & protects mass air flow sensors
Plastic safe & leaves no residue
Improves air/fuel ratio & increase MPG
Safe on sensitive equipment
Increase horsepower
Reduces rough idle
Decreases hesitation & pinging
Entire job takes less than 10 min

Don't use aggressive chemicals like brake parts cleaner or carb cleaner on MAF sensors. These can cause serious damage to sensitive parts'

You can get CRC MAF cleaner at O'reilly's. When cleaned my MAF with it, it seemed like it had a faster throttle response but that could be just in my head.

I used the CRC MAF cleaner as well. Also used it to clean my IAT. Dries in less than a minute, leaves no residue, so you can clean it and reinstall it right away.

I picked up some CRC QD Electronic Cleaner from Pep Boys just now. I saw the regular "Lectromotive" stuff, but this seemed better suited to the task. I also needed it to clean the contacts on a cell phone :chug:

I'll post back once I try it.

I wouldn't use carb cleaner since it has oil in it to lube the carb parts. I would use the MAF cleaner. Cheep insurance, since I har MAF sensors are spendy.

Just did it, the wires were surprising clean already :( Hopefully this will still help. Be pretty cool if I pick up a few mpg. :drive:

Just cleaned mine. I used the CRC MAF cleaner, I figured it's well worth the $7 to use the right stuff, MAF sensors are very expensive, and delicate. The sensor has three little elements, and I could see that two of them were gunked up on the intake side. I tried spraying them down a few times, but the gunk was still there, so I took a q-tip, sprayed a little cleaner on it and gently wiped the ends down to get the gunk off. Just took it out for a spin, I don't notice any difference. It used to knock a little bit once in a while under heavy throttle at high rpms, I didn't notice any of that. Regardless, I feel better knowing it's done.

I also cleaned the MAF on my Ford Escort with the same stuff. That car was knocking a little in warm weather, I will have to wait til summer to see if it's fixed. One thing I noticed on that car is that one of the ends looked whitish, almost like it was corroded or something. It looked a little better after I sprayed it.

I have the stock MAF sensor which has not been descreened. Can I just take off the air filter housing and the rubber boot up to the maf sensor and leave it on the car and spray the CRC cleaner up in there or do I have to disconnect things and take the sensor out of the car completely? It is my first time trying this. I overoiled my K & N filter and now I have a rough idle on cold starts.

CRC MAF cleaner.

But I DO recommend using a Q-Tip to clean them 100%. Bend the tip 90 degrees and GENTLY whip the thin sensor wires on the incoming air side. You're not going to break them unless you really push/pull hard on them. Just be gentle. The MAF sensors WILL get cleaner. Dirt over the years gets caked on and builds up alot.

A can of CRC MAF cleaner goes a long way. You can propably get a dozen cleanings out of a can. Make sure you unplug the MAF and keep your damn keys away from the ignition, you don't want any power to the MAF.

And I am going to respectfully disagree with RPM WS6 about the Q-tip cleaning. You really should not touch the wires with anything unless you are VERY carefull. I know you are, but it's not the best advice for everyone. Repectfully. :D

It really only takes a few minutes to remove the MAF sensor. I would remove it and clean it out.

But I would like to warn you, one of my instructors (who worked for GM for a very long time) told me that even MAF cleaner can leave a thin residue leading to a slightly false reading. He said the best way to clean them is rubbing alcohol and a Q tip.

When I removed the air filter lid there was quite a bit of bugs and trash on the screen to the MAF. I took a purdy soft paint brush and gently brushed it off. I assume this screen is not the part that is delicate anyway. My mechanic said use q-tips and alcohol too but everything seems to think not to touch the wires. I ran out of time so I put everything back together and I will wait until I have more time. My car is not real bad but it has changed since I reoiled the filter which I discarded since so I would not be making it worse.

Fix your lid, it is not sealing properly.

The rubber boot that connects to the lid I noticed yesterday has seperated on the bottom side and I tried to fix it back. It won't go back like it should so I am going to get a new piece one next week. I have a friend that works at GM and hopefully I won't have to buy the whole lid. It is a very small seperation. I can't believe it would have sucked in that stuff there but I guess it did.

Is this a stock lid? If you're going to spend any money on it I would consider getting an aftermarket lid instead, you will pick up about 10 hp.

Im sure the K&N Filter is your problem, all that oil is hitting your MAF along with your lid not sealing properly. If i were you i would just stick with a paper filter. From what ive heard, the K&N filter really isnt any better then a regular paper filter and for $70 bucks (price i saw for a K&N). That bitch can stay at the store lol Get yourself a can of MAF cleaner from Advanced Auto Part's and just spray the MAF down. It evaporates and dry's by itself and no need to worry about touching the wires.

You heard right. No way possible for a K&N filters anywhere near as good as the ole' paper filter. And that 1-2 hp increase that the K&N suppossedly gives just isn't worth it at all. Dirty MAF's and more engine wear. Its a no brainer. But they certainly do market those things well to make sales like they do :D
