Don't do anything major until you get my care package, but in the meantime:
Check to see if you have between 4 and 6 volts at Pin A of the MAF sensor (yellow wire).
Do you have a code 34? Probably not.
Ignition on, engine off, disconnected MAF connector, you should read 4-6 volts at Terminal A (yellow wire). If not, it'* wiring or PCM at fault.
If yes, check for 12v between B and C (pink/black is C, Blk/Wht is B....B is ground).
The FSM gives no resistance readings of the filaments. Nor any diagram for the INSIDE wiring. It shows only 3 wires are used, but I recall 4 in the connector? I'll have to check.
