O.k. This is generally caused by the mass air flow sensor, that's always first. There is a small belt driven air pump that has a couple of hoses that come off of it and route to the intake (or to the top of the engine) and the exhaust, there are in line check valves on the hoses. This system directs air either to the heads or the cats (catylatic converters). Check to see if the pump has gone out, a check valve is stuck, a hose has collapsed or is cracked/broken allowing air to escape, or if a vacuum hose, that runs to it, is cracked/broken or come loose, and sucking air. This is just an emissions requirement, and when this happens it generally doesn't make the car run any differently, it just throws a code. CHeck these and let me know

    ok lets start with the codes they say your getting. P??? which 1's and how many. there are few o2 sensors, are they next to the Exhaust next to the converter? MASS AIR FLOW -MAF use this, for now i am guessing, until i see the correct codes your are getting. this could be the 1 you may have below, please read it........

      Mass Air Flow Sensor Circuit High Input
    • Possible causes
    • Faulty mass air flow sensor
      - Intake air leaks
      - Dirty mass air flow sensor
      - Dirty mass air filter
      - Mass air flow sensor harness is open or shorted
      - Mass air flow sensor circuit poor electrical connection
    • Before replacing the mass air flow sensor, try replacing the air filter and cleaning the air flow sensor with low compress air or mass air flow sensor cleaner. Reset code and drive vehicle. If the code comes back, it may be necessary to replaced the mass air flow sensor.

    Where is mass air flow senser on a 1989 buick regal


    Hi

    Thanks for using FixYa. The BUICK Regal Mass Air Flow sensor is usually installed in the intake air duct between the air filter and the throttle body mounted on the intake manifold. Also check the throttle body for mass air flow sensors location.
    On mass air flow sensors with a sense wire, this wire can become contaminated with dust particles. These particles can be removed with automotive solvents that are safe for the use on mass air flow sensors. Before replacing the mass air flow sensor check for air leaks in the connecting air ducts and intake manifold. These leaks can cause similar symptoms as a malfunctioning mass air flow sensor.

    Bad or contaminated BUICK Regal Mass Air Flow sensor can possibly cause a wide range of various vehicle drivability problems such as stalling, especially when the engine is cold, misfiring, poor acceleration, etc. In addition, a problem with the Mass Air Flow sensor often causes the "check engine" or "service engine soon" light in the vehicle instrument panel to illuminate.

    Please do accept the solution if the issue is resolved or else revert for further assistance.

    Thanks
    Rylee
