I am assuming you only get the MAF sensor on the 3.0 turbo so I'm guessing it has something to do with a fault on the turbo or blocked filter. which causes a loss of power.

As robo has said above, the MAF sensor measures the amount of air that is entering the engine and sends the info to the cars computer which then calculates how much fuel to add in order to get the correct air/fuel mix.
All EFI cars have a MAF sensor.
