DIY Cleaning MAF Sensor!

I just tried helping out another member and figured it would be useful. Sorry for the bad pictures, I did not have enough lighting and my camera is not the best.










I forgot to add this step. This step is very important.
Be sure to clean these items too which are on the MAF sensor as well.

You forgot one more very important part (I know it's been mentioned in several of the other MAF cleaning how-to's). Be sure to spray the electronics cleaner on the two tiny filaments inside the cylindrical tube part of the MAF sensor.

This picture should help:



Just don't shake yours to dry it after spraying. Here's the URL where that picture is from

Yes indeed, that is the most critical part of cleaning MAF sensor, without that step, the MAF sensor is still dirty.

after cleaning

has anybody noticed any difference after cleaning their MAF?
Was yours visibly dirty before cleaning?
sometimes with the power button on, my car sort of stalls before it shifts after 3k rpm with auto. I was thinking of doing this to see it it helped. thanks for any input
