Where are the MAF sensors from?
Do you have a K&N or oil type air filter?
Any MAF you buy from an auto parts store (as far as I know) will be remanufactured. So it was already "bad" once. What did they do to fix it so it can be sold again? I'm not sure.
My personal experience, I had one from Autozone last a year. I replaced it with one from NAPA because the NAPA one has a LIFETIME warranty (with receipt). So they have a pretty high opinion of their part to offer that kind of a warranty. It's been fine ever since.
In your case it could be a connector issue (loose wire or bad contact) or it could be another bad MAF.
Oh, and welcome to the forums!
