There is not a MAF sensor. There is a MAP sensor. It is located on the drivers side of the intake. It will be a black rectangular box with a green connector. The connector will have three wires.

SOURCE: Mass Airflow Sensor 2005 Chevy Malibu. 2.2 ltr.4 cyl.
The MAF is in the flex hose that delivers air to the engine, it has a 5 or 6 wire connector going to it.
SOURCE: My 97 Chevy 1500 runs but it will sputter and shut off .
Check the distributor cap/wires/spark plugs. Also might be clogged injectrors (injector cleaner)
Hope that helps
Good Luck

Hello l_anderson36: My name is Roger and I will help you. You should find the map sensor at the front of the engine. Located on the drivers side of the engine. The sensor will have a plug with three wires on it.

Most likely if there is no mass air sensor you actually unplugged the inlet air temperature sensor IAT. This is a little bead like thermistor that sits in the ducted air stream to measure incoming air temperature. Without an air mass sensor your engine will have instead a manifold absolute (air) pressure MAP sensor. This measures the absolute air pressure (the difference between the atmospheric air pressure outside and the drop in pressure inside) in the inlet manifold. The drop in pressure in conjunction with air temperature allows the engine control unit to calculate the amount of air in the engine to which it adds the correct amount of fuel per each injection cycle. The loss of the IAT signal is not critical as the ECU will assume a default value. However when extreme low temperatures are encountered the absence of the IAT may be become noticeable as the charge of air entering the engine will be denser and as a consequence the fuel mix will be much leaner; maybe to lean to start up.
