Can you clean a mass air flow sensor?

Yes you can by using Mass Air Flow Sensor Cleaner

by CRC. Kragen Auto Parts sells it. This is what the Mass Air Flow Sensor Cleaner

by CRC looks like (http://www.autobarn.net/maairflsecl1.html) you can order it online too. After you clean the mass air flow sensor make sure to reset the check engine light. You can reset your check engine by going to Auto Zone or Kragen Auto Parts and ask to borrow the code reader* (it's free all you need is your ID and credit card) to check out the code reader.
