problem #3

LeSabre Limited 3.8L V6

  • Automatic transmission
  • 125,000 miles


All you need to do is to locate the Mass Airflow Sensor on the intake throttle body. Unplug wiring plug. There are two screws that hold the sensor. The screws are security screws, the star with the raise "O" in the middle. Unscrew those two, pull the sensor straight out, pop the new one in, put the two screws back in, and plug the wiring harness in and you are ready to go. Its about a 5min job, 10mins at the most.

This car is very dangerous. I can be driving down the street and it will suddenly stop. When I pull over to the side of the road, I can re-start it. This has happened 8 times over a period of a year. I have taken it to the Buick dealer twice and they said they can't find anything wrong. They said that they could keep the car for a few weeks and test drive it each day to see if it will fail again for them.
