Replying to: jipster (Jul 23, 2007 5:27 am) I will give that a try. The MAF sensor was pretty expensive but I wouldn't doubt it would go bad being a remanufactured unit. Do you think I should try to get a new unit and not one that is remanufactured? Thanks Replies to this message: jipster (Jul 25, 2007 5:50 pm)

Replying to: fondo (Jul 24, 2007 6:36 pm) Perhaps the place you bought your remanufactured unit would replace it for you if you told them it was not working. Did it come with any type of warranty?   Hard to say about getting a new one. Funny though that's it's not putting out a code. It cost me around $350 at my Buick dealership for a new MAF sensor, I think that included $90 for diagnostics.

Replying to: fondo (Jul 22, 2007 3:24 pm) I'm having the same issue. We were driving my '98 Buick Regal and all the sudden the car just dies, no power steering nothing and couldn't get it running again. We had to rev the engine throw it into gear and keep the RPM's above 2 just to make sure we got it home. (We were in a no cell phone zone in the mountains!!) Once we got home the car ran just fine!!! HOW FRUSTRATING!!! Check engine light was on until I was almost to the mechanics and wouldn't you know the dang thing went off right before I got there. So he checked the codes and memory and there was a Mass Air Flow Sensor code in there (so he tells me). So I just picked my 1998 Buick Regal up yesterday from the mechanic who put in a new Mass Air Flow Sensor. I took my car up some hills to try and put a load on it to see if it would happen again. Nothing but a crackle noise when the car is in second, which I've heard before but not as much. And my Service Vehicle Soon light came on, not the Check Engine Light. Any ideas what this might be? I'm ready to drive it off a cliff! Any suggestions on the issue would be great!!!!
#11 of 15 Buick Regal Mass Airflow Problem by diy_dad Aug 28, 2008 (12:23 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 Replies to this message: jipster (Aug 29, 2008 5:02 am)

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!
#13 of 15 04 regal service engine soon light by micheman Dec 14, 2008 (5:18 am)

Car has 59000mi. Is there a check to narrow down which components are bad. Car does not have a turbo and never has.

Replying to: fondo (Jul 22, 2007 3:24 pm) 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.
