thats correct, however, as it is going bad, it makes the ECU do weird things.
Nissans do weird stuff to keep themselves alive.
If the MAF is just going bad, then it could be sending the wrong signal to the ECU but not wrong enough to trip the ECU into thinking the MAF is bad, and therefore is making the ECU dump way too much fuel to compensate for the tweaked out MAF signal. get to about 4k and the motor just chokes itself out on fuel.
strange things can and quite often do happen
