The mass airflow sensor is always on the air intake has wires plugged into it and when you look inside it ,it has either 3 or 4 thin strips of metal or a honey comb look,thats want you clean....bty cleaning it usually doesn't help.

Where is the mass airflow sensor located on a 1997 Buick Skylark 2.4 liter

Right off the air box its the first sensor on the vehicle .
The air is sucked through the air filter then goes through the mass air sensor so its in the air duct .
They have a spray can cleaner you have to remove the clamps and connections and remove it .Spray it with the cleaner some times it works .
Its a rather expensive part but its vary important because it is the first sensor that the computer reads to adjust all engine controls .
Also don't through it away you will get a lot for the re core value.

How to troubleshoot air fuel mixture problem on 1989 lesabre

If your car has a MAF sensor, it is in the air intake hose between the intake and the air filter.
If the check engine light is on, you would need a scanner to read the computer data coming from the sensors to diagnose the problem.

Dose the buick park avenue use a map sensor or a mass air flow sensor. or are they the same thing

They are different types of sensors, but in your car the MAP (manifold absolute pressure) sensor, along with the BAROmetric sensor are used to estimate the required fuel flow through the throttle body injectors. These sensors measure pressures inside and outside the engine to estimate airflow. You do not have a MAF sensor. These are more common in later vehices with mulit-port fuel injection. A MAF sensor actually measures the airflow into the engine using a hot wire anemometer. You are correct in believing the sensors serve the same purpose, that is to calculate the fuel flow required for stoichiametric combustion. The oxygen sensor also feeds back to the computer to further refine the fuel charge by measuring oxygen in the combustion products. If excess oxygen is detected, the fuel charge is increased. This is known as closed-loop operation. Closed loop operation is not started until the engine is at operating temperature. If you have more questions, please let me know. I have pasted the location of the MAP sensor below. The sensor is mounted to the air cleaner, but it has a vacuum hose that leads to the throttle body, which is where the pressure must be measured.
