Okay, so 3 months ago I got my 95 mustang gt 5.0l. It was in bad shape... I fixed it up and the motor would act like its struggling to stay alive. Upon reading I found the MAF sensor is known for going bad on these cars so I went to advanced auto parts and bought a new one. It's ran 110% better until yesterday, a month after I bought the last MAF the car died and left me stranded again doing the exactly same thing it was before. I took off the MAF sensor and exchanged it since it was still under warranty and once putting the new one on guess what, it's running perfect again! Why does the MAF keep going out on it! It's a bone stock car, doesn't even have a CAI... PLEASE HELP ME, it's my DD and I can't afford to miss work if it ever goes out on a week night

 

Any chance the car has excessive blowby and is gunning up the MAF sensor?

 

I'm not sure what you mean by blowby
It has a stock air box and tubing with a k&n filter
And spraying cleaner on the MAF will not fix it, only replacing it will it then run good again

 

By blowby, I mean are the rings worn, allowing excessive crankcase pressure, resulting in higher than normal oil vapors to be pulled into the intake tube, contaminating the MAF?

 

I mean, without tearing the motor out if have no idea, it only has 124xxx miles and it's never been beaten
