Mass Air Flow Sensor Cleaning

[hotwheels]

If you have had bogging or missing or idle spots, about every 25K miles plan on this quick cleaning job:

When your engine is cool, remove the wiring clip from the side of the black plastic sensor part of the MAF aluminum body. To remove the MAF interior sensor wire, you will need a Security Star (Size T15 or T20) screwdriver or screwdriver bit for a power screwdriver. Remove the two security star-head screws and carefully remove the sensor. You will see the two sensor filaments, they look almost like the filaments on a light bulb. Carefully spray the filaments with an O2 safe carburetor cleaner, such as Gumout. Let it dry thoroughly. You can help it along with a careful blast or two of canned dry air. While it is drying carefully wipe the aluminum mount surface of the MAF body if there is any dust there, but be careful not to get dust in the mount hole. When the sensor is dry, replace the sensor back in the MAF body and secure with the security star-head screws. These don't need to be torqued down, just simply hand tight. Replace the wiring clip. Then start up your engine. You should have solved any bogging or missing problems.

best way to see if you need it,if yo have a scan tool , you can read the cal load, under full throttle you should be up to or over 100%, if it reads lower the worse the meter is.sometimes cleaning will help but no get you 100%... and no carb clean.. use maf cleaner
