#21 of 30 Buick Regal Mass Airflow Problem by diy_dad

Aug 28, 2008 (1:23 pm)

I found this site on cabelas forum, http://repairpal.com Punched in 2002 buick regal mass airflow replacement and it said, About this Repair: Mass Airflow Sensor Replacement for your 2002 Buick Regal
What to watch out for
 
      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.
    *
      "High-performance" wet foam air filters are not recommended because they will damage the mass airflow sensor and actually cause poor performance.
 
Recommendations
 
    *
      The air filter should be replaced along with the Mass Airflow Sensor. Dirt and debris should be cleaned out of the system to prevent any damage to the new sensor.
 
Why this happens
 
    *
      A failing mass airflow sensor can cause the "Check Engine Light" to come on and due to high nitrous oxide, the vehicle may fail an emissions test.
    *
 
      If the Mass Airflow Sensor is not functioning correctly, the vehicle may lack power when accelerating or going up hills

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!

04 regal service engine light stays on. car runs great, gets good gas milage. 5 codes say (paraphrasing) rich mixture bank 1 (2times) transmision shift solinoid (2times) and turbo malfunction (1time).
Car has 59000mi. Is there a check to narrow down which components are bad. Car does not have a turbo and never has.

i read on this site to check out if the CAT converter is plugged. apparently there is two lines running to it and they crack over time? check it out. also known for helping transmission.

Like a lot of you my check engine light stays on..low tire stays on inside dash lights not so good sometimes fog lights work Hi-beam is what I use all the time because, tried replacing the drivers side lo beam- worked for a bit, then both now don't work, even with new bulbs. someone mentioned fuses-- mine are under hood and I have no manual and I'm a broke girl $$$ can't do expensive hoping someone could share their fix its
 thanks Pam
Everything else works pretty well. Only had the car 4 mos. I sat in a tow yard I believe for couple of years. Thankfully it just doesn't stop

turn ignition on. in fuse box is tire pressure relearn button. push it and you should be good. make sure tire pressure set correctly when doing this. some auto stores will check code for check engine light for no charge then at least you will know what is wrong.
