Q: Are aftermkt mass air flow sensors any good.Replaced 3 times in last year? on 1999 Pontiac Bonneville

The 1st time I had a problem it got to where it wouldn't run ,replaced the mass airflow sensor with a rebuilt autozon sensor,it ran perfect for 6 months and it started doing it again,got another 1 and it lasted about a month and it started messing up,went and got another one but new ,ran perfect for 2 days and stalled one time.Does not die all the way just stalls for a split second and a low fuel warning bell dings 3 times and then it runs fine after that.Thanks for any help.

I agree with overbys' statement. We stopped using AZ parts many years ago. You get what you pay for.

No,Im not sure of the diagnosis.I just know that the 1'st one got so bad that the car would not run and when I replaced the mass air flow sensor it ran fine for a while.I am going to go ahead and replace the crankshaft position sensor and both oxygen sensors(for better gas mileage) and if that doesn't fix it I"ll get a factory mass air flow sensor.Thanks for your help.
