Have you replaced the 'wiring-harness' (w/h) on that car?? You can inspect it to see if the wires are cracked and brittle. A good place is where it ties into the MAF sensor. Loosen the connector (quarter turn) and remove it. Use a 'xacto' knife (or eq) to open the 'sheath' so you check the wires in the bundle. If OK, tape it up.

If the w/h hasn't been replaced, I suspect it's in bad shape and needs to be relpaced before you go further. A bad W/H will cause all kinds of problems.
