I am having a problem with my sons 99 grand prix. The other night it started then died, started then died, then died completely. Uplugged the MAF sensor it started and ran fine. Replaced the sensor, and it ran fine for about three days, then started doing the same thing. Went back to the auto parts store, and they replaced the MAF with a new one. Same thing happened, it ran fine for a few days then began acting up again. Any suggestions would be helpful. It was also giving the MAF code, and the parts store cleared it out.
