Question about 1997 Oldsmobile Cutlass Supreme

1 Answer

Mass Air Flow or something else

I just had my car repaired a couple months ago and the mechanic suggested that I replace my Mass Air Flow Sensor and did replace it. Since then my car has undergone a break change and front left axle change. For those two months the car was running decent, but after the axle repair my car started acting up again. The service engine soon light has come on. At stop lights and stop signs, the car will rev on it's own or completely shut off. So I checked it with a canOBD 2 in 1, a diagnostic tool, and it it telling me that my mass volume air flow circuit has low voltage/input. Why might it have done this and how would I go about correcting this? I have to smog test my car soon and I doubt it would pass with the service engine light on. Thank you for your time.

    Had same problem a couple years ago. It was my oxygen sensor. But to make sure, take your car to Autozone and ask them to diagnose the check engine light. Could be something a simple as gas cap, or Mass Air Flow Sensor which is located on air filter housing line which is located right before air filter. Buy a spray cleaner for sensor CRC Mass Air Flow Cleaner 3-4 bucks, and see if that works. Your car will pick up some horse power. If that doesn't help then get a new gas cap. (You prob need a new one anyways). If that doesn't solve problem then it prob is the oxygen sensor. That will run you like 120-150. Replace it yourself don't take it to mechanic it is a real easy fix just make sure u don't touch new sensor. Well that's about all I can think of so good luck my friend!

    sir I am pretty sure it is the k and n filter...The oil inside the filter at times will **** through and dirty the maf sensor and throw this code...The metering cant hold a proper charge to measure air flow.I have seen this three times...I rcommend a denzo maf sensor and airaid cone air dryer or the mina gallery air dryer.These work flawless....and filter with a oil charge will cause this code.the other two codes are cyle and readiness codes that are performed by the cars ecu each time it is parked to check all modules for malfuction or codes...Remember codes are cycled between every two ignition or crank cycles unless you have complete failer of a module or drive train.

    Did you do anything to repair the mas air flow sensor code or did it go out by itself?If you did not replace it or clean it you should get some mass air flow sensor cleaner and clean it out.You can get this at most part stores.If you are getting this code then you need to repair this problem.This will cause the car to loose power and it can be intermittent.Hope this helps.Good luck.Let me know if you have anymore questions.

    Check engine light


    No the light is fine its the computer or there is a intake leak somewhere causing the mass air flow sensor to not work correctly, also a cracked hose may be giving a false reading. Get a mechanic to test it with a voltmeter and ohmmeter using a vacuum gauge to make sure it is the mass air flow sensor

    hi there, when air flow unplugged, ecu goes into limp home mode ,a back up if something dies whilst driving. it sounds as if your used mass air flow sensor is faulty , they are more fragile than they look, one knock and these early fine wire models are gone. i replaced many when i worked at a volvo dealership a few years ago. hope this helps, and good luck.
