Umm...you are aware that those aren't Mass Air 
Flow sensors, nu?  The MAF has a cobweb platinum 
wire or some such strung across the airflow and 
is happiest squeaky clean (burns itself clean 
every time it starts, I think.  Very fragile and 
doesn't move, protected from debris by some sort 
of shield in front of it I imagine?).

Our AFMs are big and heavy and move around like 
crazy.  The wiper was designed to run dry (I 
believe.  I don't think there's lubrication 
embedded in the track other than it being 
graphitish).  But the shaft certainly needs lubrication.

Been much too long since I've been inside one to 
say anything specific, so it's just a heads-up.

Yrs,
