I know that this is an incredibly simple process but sometimes I find things easier with pictures. I couldn't find anything like that on this site, there were lots of references to cleaning the MAF and I wanted to clean mine. I figured I would create a simple tutorial and give back to the community that has helped me so much.
Here are the tools you will need:
1) CRC Mass Air Flow Sensor cleaner. Do NOT use break cleaner or anything else that is not designed for electronics. About $8 at a local parts store.
2) Flat head screw driver
3) T-20 Torx bit
The MAF is located on the driver's side of the Air filter housing
Use the screwdriver to pull the red tab out. It pulls out like a drawer and not up or down like many tabs.
Gently pull the connector off the MAF. If this has never been done on your truck before you may need to use the screw driver on the red tab to give you a little more help. It should slide right off.
Next, use the T-20 torx bit to remove the two screws holding the MAF to the air filter housing. There is one on the top left of the sensor (shown below) and one on the bottom right of the sensor.
Gently pull the sensor out. Be sure to not get any dirt into the air filter housing when you remove the MAF.
Spray the MAF and let it dry for about 10-15 seconds. Do NOT touch the wires in the MAF with anything other than the CRC cleaner.
To put it back follow the procedure in reverse order.
Cleaning the MAF is a good idea every time you change/oil your air filter as it can get dirty from all the dust and oil that may come through your air filter.
If you have any questions or there is more information I can add to this tutorial let me know.

Great short & to the point write up .... I too need to do this, I need to get the CRC first as I keep forgetting and everytime I think about it, still need the spray.
My 07 has near 40K and it's never been done either. I doubt it's ever been done on the '95 TBird at 75K and I know it hasn't on the Merc or Subaru. Maybe on the '92 TBird .... loooks like I'll use up a can .... haha
Gotta get back up there to the Frost Diner here soon! Get some Hank and Lefty going on the juke ....

will this help with fuel cost? i have a 2008 f-150 5.4 v-8.i chipped it and gained super hp and some fuel economy.
Cleaning the MAF helps the sensor be as accurate as possible so you get the right amount of fuel for the amount of air going through your motor. A dirty MAF can misread the amount of air, but it is more likely to cause a lean condition (not enough fuel) than using too much fuel. It is a good maintenance procedure to keep everything running smoothly, but don't expect to gain any noticeable MPG.
Nice write up Dog. And just to add, for those of you running with a CAI or permanent washable filter, especially do it after re-charging or cleaning the air filter and or check it after you've put the filter back in and driven the truck. Your supposed to let the filter set and the charging oil dry properly, but I have seen where some might not wait long enough for that and after running the truck, some of the charging oil will get on the sensor, sometimes that will happen even after it does dry long enough, I've seen it happen. Anyway, that will mess with how the sensor is reading the a/f mix, just my 2 cents (and it's not even worth that )
I see its been a year but i just came across it.
Do you just spray into the hole where the wires are or do
you spray the whole thing. Also, do you spray sparingly or
do you wet it real good. Thanks!
