You should clean your Mass Air Flow Sensor every time you change your air filter or clean your reusable air filter.
NEVER TOUCH THE METAL PART OF THE SENSOR. OR ON OLDER STYLE MAF NEVER TOUCH THE METAL WIRES
Some older model MAF are different design then the one in this How To. The Process is essentially the same.
Here are what some of the other MAF designs look like.
On this style remove the 2 torx screws and remove MAF from housing.

I am showing how to clean a MAF on a truck that has a aftermarket intake. Same process is used for a factory intake.
Tools Needed:
CRC Mass airflow cleaner
T-20 torx bit
Adjustable wrench or box wrench for battery
Paper Towel
MAF cleaner can be bought at any auto parts store. DO NOT USE ANYTHING ELSE
Step 1:
Remove Negative battery cable.
Step 2:
Locate your MAF Sensor.
It will be located on the intake tube. Just to the right of the air box.
Factory Air Intake Setup.
Aftermarket intake
Step 3:
Remove electrical connector.
There is a clip that needs to be compressed then you can pull the connector out.
Step 4:
Remove Sensor
There are just 2 T-20 torx screws holding it in
Be Careful when pulling it out. They can be damaged pretty easily
Step 5:
Clean the sensor.
Lay sensor on a paper towel
Inside the opening is where the "sensors" are Spray it really good. I usually Spray it for 3 seconds then wait a minute. Then hit it one more time. Let it dry for about 10 minutes before reinstalling.
