why not just tell her its the square thingy on the top of the throttle body with a plug to it? i got no pics of a maf. tap it if the idle gets funky, or clears up, the maf is likely bad.

you can also engine off, unplug the maf, then fire it up, if it runs better the maf could also be bad, or if you see bare wire or crackes in the wire insulation the wires could be bad to the mafs plug.
