Hi:
The mass air flow sensor is a round sensor that is mounted in the air intake, between the air cleaner box and the engine throttle body.
SOURCE: where is the mass air flow sensor 1999 bonniville?
It is in the air intake between the filter and the intake manifold.

It should be along the air intake. A block box about 1 1/2" x 2 1/2" held on by 4 ? screws. Easy to replace, but kind of pricey. They make a product for cleaning them. Try that first. Do not touch the wire resistor that goes into the intake. It's delicate.

3.1 liter - It will be in the air snorkel in between the air filter housing and the throttle body.
3.8 liter - it will be mounted in the throttle body right before the throttle.
Both will have a flat 3 wire connector.
