How do you change the Mass air flow on a Pontiac Aztec?

To change the mass air flow (MAF) sensor on a Pontiac Aztek, first ensure the engine is off and disconnect the negative battery terminal to prevent electrical issues. Locate the MAF sensor, typically found between the air filter and throttle body, and carefully unplug the electrical connector. Remove the screws or clamps securing the sensor, replace it with the new one, and reattach everything in reverse order. Finally, reconnect the battery and start the engine to ensure proper functioning.
