I am a newbie and a owner of a 2k GLE. I have read many treads about MAF failure and symptoms. I am confident that my MAF is dirty or just needs replacing. I am also confident in my ability to do the job myself and save some $$$. The problem is that I have never seen the type of screw heads (star shaped but not the "hex" star type) and was wondering if anyone here knows where to buy the driver OR if something else will work. Also, is there a "how to" on the whole proceedure? Any input would be great. Thanks!!!

 

Any automotive store will have em. I bought mine at Strauss Discount Auto. Procedure is simple: unscrew the screws, pull out the MAF. It will not be easy to pull it out b/c there is a rubber ring at the base. I used a flat head screwdriver to help it out. Mine had a bit of tan ash or dust on the metal pin, so I used a qtip to wipe it off. Cant say it helped but YMMV.

 

Thanks 420. That helps a lot. Hopefully my max will be pulling strong (above 3,800 rpm) again soon.

 

dont forget to disconnect the harness

 

the star-shaped tool is called a "torx" head.

btw-what makes you think your MAF is "dirty" and needs replacing? Is it blown?

If you are just getting weak pull in higher rpms, there's alot of things it could be, but MAF doesn't sound likely. Either it's good, or it's bad. Could be bad coils, bad injectors, etc etc etc....

 

I found the tool last night at sears. A lot of other places had it but it did not have the little hole in the middle of the driver head. Anyways I took the sensor out, used a slightly modified q-tip and some rubbing alcohol (it was a little dirty in there) and put it back on. MAN what a difference!!! It pulls VERY strong in the upper revs. Apparently the damn thing has been dirty since I got the car in Dec. Thanks for your input guys...now I have a smile on my face when I punch it!

 

NEWSFLASH: Blown MAF Myth Blasted! New study reveals naughty MAFs are just a little dirty.

 

im going to try this today myself, im getting severe hesitation at EXACTLY 3400 rpms and above.. would anyone know what torx bit size/number the MAF uses?

 

The 2k's use a T20 size. Make sure that it has a hole in the middle of the hex. Also I wasn't able to find the single and had to buy a full set at Sears for $20. Good luck!

 

BTW a standard q-tip won't quite fit between the sensor and the plastic housing. Make sure that you flatten the q-tip head so it will fit...be very careful with the sensor. You may need to remove most of the cotton from the tip for best results.

 

did the problem start suddenly or did the car start feeling sluggish gradually?


my car suddenly started driving like total crap.. accelerates terrible in higher RPMs.. like night and day difference, yet i get no check engine codes..

i am going to pull that sensor tomorrow if i have time and clean it up..

 

I bought the car in December and it always felt weak as the rpms moved past 4k. I just felt like it wasn't accelerating like it did off the line. It kinda felt like it wasn't getting fuel. The difference after cleaning the sensor is amazing. When I floor it no matter what speed it pulls strong all the way to redline.

 

BTW I never got a SES either.

 

i cleaned the maf last night, and i def feel the car pulling strong again, still think i got bad coils though

 

exactly what i'm experiencing now

only i knew how quick the car can be when it runs right.. all of the sudden it just got really sluggish.. now i'm driving it around for a week with this problem and i am starting to forget how fast it can be
