Your close but your getting things the wrong way round. If the MAF is faulty then it will cause miss-firing and loss off power. In order to identify that it is the MAF at fault, you unplug it. If it runs better then you know its the MAF.
For your info, when unplugged, the ecu will account a base fuel map which in turn means the car will fuel more, not less like you suggest.
