Clean the mass airflow sensor with a special spray cleaner meant for the job. Any other kind of cleaning spray will destroy the sensor..

I have a Buick lasabre 3800 and on my mass airflow sensor one wire is clean and one lookes burnt . Would that cause my car to act up?


Yes, a dirty or bad mass airflow sensor can cause a car to run badly. I had a 1999 Mazda Protege that had this problem. You can get a can of mass airflow sensor cleaner from an auto parts store. Be careful to hold the can a few inches away from the wires so as not to break anything. Mass Airflow Sensors are fragile. Let it dry before putting it back in the car. If your car has the check engine light on, they can check the code for your as well. You could go to Autozone, Advanced Auto Parts, Oreilly's, etc. CRC Mass Air Flow MAF Sensor Cleaner Instructional Video

When I get to 60 mph or when I first crank up my 2000 Buick lasbre stalls.


First check fuel pressure to specification. My suggestion is a faulty mass airflow sensor. At idle lightly tap on mass airflow sensor with screwdriver handle and listen for erratic change in engine rpm. Wiggle airflow sensor connector and listen for any changes also. Replace sensor if rpm changes.

I have a 1995 buick lasabre it starts then cuts off whats the problem


A failing crank sensor can do this a failing CAM sensor can do this or even the ICM (ignition control module where the coil sits at).If you want to fix this the best tool is a labscope.But if you want to do the most likely problem and go from there do the ICM (ignition control module)

1999 buick lasabre hesitation while driving.


there are really only 2 things that cause this problem most of the time i have seen it, 1st a defective Mass Airflow Sensor, the second is low fuel pressure from a failing pump or obstructed fuel filter do u have a check/service engine soon light on at any time? have u had the system tested for trouble code's? Go to any Kragen or Autozone and ask for a OBD 2 trouble code test, it is free, record any code's that show and post them back here on this same thread.

1997 buick lasabre custom high idle, transmission, stalling


Try cleaning your grounds under the hood: under Ignition Module bracket, rf fender behind battery and lf fender in front of windshield washer fluid bottle.
I had similar problem and this fixed it.....grounds are very important for computer.
I used a carbon conductive grease on the connections to keep them from oxidizing.
Hope this helps you out.
