The Mass Airflow sensor is held in the air intake hose to the engine from the air cleaner by 2 approx 4" large hose clamps, unplug the connector to it and loosen the hose clamps on each side of the sensor and pull off flexible air intake hoses on each side of the aluminum body of the sensor and remove the sensor assembly. See picture below.

It is inline with your intake tube, unscrew the clamps on both sides of it and remove the harness connected to the MAF, installation is in reverse order-an easy job.

There are 12 common sensors and 10 internal sensors. The most common that often fail (MAP), (TPS), (CAM), (IGN), (CRANK) MAP is your mass air flow which is located at the beginning of your air intake, TPS is the throttle body position sensor, the CAM is the cam shaft position sensor (transmission), IGN ignition position sensor and the CRANK sensor is located near the bottom driver side front

2001 pontiac montana dies when let off gas p0102 code

Code 102 is for a problem with the mass air flow meter circuit.
The sensor is saying the air flow is very low.
Could be the sensor or a leak in the hose between the sensor and the intake.

2002 Pontiac Montana stalls in stop-and-go traffic especially on a down hill grade. Have changed gas filter. Diagnostic didn't find anything unusual.

First off, when was last healthy tune up? Plugs, plug wires, ALL filters and a good fuel system cleaning? I'd start there, then have parts store like Autozone, Advance etc.. do an OBII fault scan. I'm suspecting of tune up doesn't help maybe an oxygen sensor or a MAF (Mass Air Flow meter) are strong possibilities. But tune it first, and get scan done before just throwing parts at it.

3200 v-6 really rough running backfire through

check the mass air flow sensor in the air cleaner tube,it may have a white piece of fuzz on it from the filter and it changes the readings of how much air its getting.
