#12 of 15 Re: Buick Regal Mass Airflow Problem [diy_dad] by jipster Aug 29, 2008 (5:02 am)
Replying to: diy_dad (Aug 28, 2008 12:23 pm) Mass Airflow Sensors are often replaced when the only problem is a bad connector or the sensor wiring harness. The shop should check these items before replacing the sensor.   I had my MAS replaced a few years ago to the tune of $300. I'm sure the dealership checked for bad connections and only replaced it if necessary... not!
