bad wires or plug can and will throw the same code for the maf as the wires get whats knows as dry wire. when you have missing insulation or cracks in the wires the wire turns brown, and is no longer shiny and no longer passes current properly.
i had to cut my pig tail back to 2 inches from the harness, the dry wire had spread pretty far down the wire. as i was stripping the wire it was just dead brown wire, kept on stripping till i hit clean shiny new looking wire, and soldered it on a new pig tail i got off ebay. for about 10 bucks.
