sb,

The MAF slips into one side of a rubber connector (collar) and the the other side fits over the throttle actuator. Both are held tightly with the large clamps. If you loosen the clamps, you can pull the MAF straight out. Over time the rubber hardens and you will probably rip it apart when you pull the MAF out. The actuator is held down with 4 bolts. After removing the bolts you can work it out of the upper intake by turning it sideways and swearing a lot. To replace you will need the manifold to TA gasket and a new rubber TA to MAF collar.

My actuator is fine after 114K miles even after I pulled it out to replace the rubber crankcase ventilation hose that connects to it on the bottom rear. I wouldn't mess with it unless I had to. The more the wires get moved around the more chance for problems. The wire bundle connected to mine was still nice and pliable with no crispy parts.
