good thread, and info
just wanted to add my 2¢ for those who want to clean
their MAF sensors.
When I do mine, I take mine off completely
I use white vineger (a mild acid) to clean mine.
Its cheap, works great and plenty of it around.
You can even soak the wire in the vinegar in a bowl
if you want for a few hours..
And when done just rinse it off with warm water.
Let air dry and install.

Triathlete, you should try to swing by my shop
someday. Its on 1st ave just north of Grant rd.
