If you needed one, I'd expect you'd have a CEL and fault codes. Performance would be down too. I think they are part of the emissions system. Cost about $762.00:

Mike, what codes do you have? Post them here. It may not be the MAS. You don't want to just start replacing parts, that are expensive, until you know what's going on.
I meant to say performance would be "down" not "done".

AFAIK, The mass air sensor detects the amount of air entering the engine and is used to judge how much fuel to inject etc. I believe it is a hot wire and temperature sensor so that with more air, the temperature decreases/changes giving an indication of how much air the engine is consuming. On older cars it was simply a trap door that would open to allow air in and how much the door was open told the computer how much air was entering.

The car generally runs quite poorly with a bad maf. Odd idle characteristics, stumbling at light throttle, poor performance, poor gas mileage etc can all be signs of a bad maf.
Before you replace it, try cleaning it with CRC Mass Air Sensor cleaner. If that doesn't help, skip right over suncoast, and purchase it here:

I just saved you $350

As basal correctly noted, the MAF has a wire that is heated to a certain temperature. When the air flows over it, the wire is cooled by the air, and then the computer reads how much voltage is necessary to keep the wire at the pre-set temp. Typically once 5 volts is reached, the sensor is "pegged" and additional airflow cannot be measured. This is then paired with fuel tables in open loop operation (engine cold or at WOT), or 02 sensor data in closed loop operation, to give you the desired air fuel ratio.
