Thank you for asking your question on JustAnswers,
This is a different expert and I think I should step in to assist you. The code P0102 in most cases isnt a bad MAF sensor. It is in most cases the connection to the power source or loss of power to it so lets start here.
Both Red wires come from the same source, which is the Electronic Engine Control (EEC) power relay. trace the Red wire for a poor connection. It comes out of the EEC power relay, which is in the engine compartment fuse box, runs to a splice in the harness below the fuse box, then splits off into 8 Red wires, one of which feeds the MAF sensor. If the poor connection cannot be located, another option would be to splice into the Red wire at the IAC, and run a new wire to the MAF sensor
Recheck the test I sent you and see what you or your mechanic find.
