Where is the mass air flow sensor on 91 Buick century?

On a 1991 Buick Century, the Mass Air Flow (MAF) sensor is typically located in the air intake system, between the air filter housing and the throttle body. It's usually a rectangular box with a wire harness plugged into it. However, the exact location might vary slightly depending on the engine size (3.3L or 3.8L).

To be certain, you should:

* Consult your owner's manual: This is the most reliable source for the exact location of all components in your specific vehicle.

* Use a repair manual: A Haynes or Chilton repair manual for your year and model will have diagrams showing the location of the MAF sensor.

* Look online: Search for "1991 Buick Century MAF sensor location" along with your engine size (3.3L or 3.8L) on sites like YouTube. There might be videos showing the exact location.

Be cautious when looking for it. The air intake system can be hot, especially after the engine has been running. Let it cool down before you start investigating.
