Cleaning MAF while in it's housing?
Hello everyone and can I do this? I managed to remove the electrical connection and removed the large plastic tube held on by the 2 clamps. The MAF is held on by another clamp which l loosened and gave it some tugs. The housing wont give so can l just spray cleaner on one side and hope for the best? The inside didn't look dirty at all so should l leave it alone? In the video it looked like a simple job but the housing isn't cooperating. Thank you.

Are you having some problem or just cleaning it as a preventative measure ? I wouldn't spray MAF cleaner on it while its still attached to the throttle body air dam. I yanked my MAF off a few months ago, when my car was running weird. I realized one of the clamps on the MAF was a non-standard design, as opposed to a normal worm gear. Once I got it off, it wouldn't go back on correctly. So I just had to buy a generic clamp to reattach it, which worked fine.
As long as your car is running okay, I would just leave it alone.

My MAF was difficult to get off as well, so don't think you have an uncommon situation. I was expecting it to come off easily, but likely due to years of it being in place without having been removed the plastics may have fused a bit.
Make sure the large clamps are wide open and then rotate back and forth several times (along the lines of from 3-12 o'clock, and back again from 12- 3 o'clock) - it should rotate- then using that same back and forth rotation add a pulling motion as you rotate and you should be able to get it apart. That's what worked for me. I think it is best to clean the MAF spraying both sides. And of course you should use a product specifically designed to clean the MAF as it is a delicate electronic component. Good luck.
