Somebody should come up with a MAF interpolator for this vehicle.
In case you don't know what that means, basically an electronic box is used
inline in the harness which then plugs into a MAF sensor.
MAFs have no moving parts and in theory should last longer.  They should
also give a slight increase in power as there is no flow restriction.  Also,
if the interpolator is calibrated for a common MAF, well then you have a
cheap source for air flow measurement.
