well the egr could be stuck open acting like a vacum leak,,,and causing the car to stall,,,you need a new egr,,,,check the wires and if any vacum hoses that go to it,to make sure they are good and connected first,if so replace the egr,,,,it could be false dtc for MAF sensor,,,

Without your actual trouble code, I am assuming that you are have a misfire on cylinder # 5. The computer cannot really tell what is causing the misfire only that cyl 5 is not putting out full power. If it misfires when cold then smooths out as it warms up, I would say it is probably an injector that is sticky, as it warms up it starts working properly.

Testimonial: "Thank you for your suggestion. I will have that checked out. I will also ask my mechanic what the actual trouble code says."
My Pontiac Grand Prix is also a 99, it has 216,+ thousand miles on it, it runs great, idles good, I need to replace the oxygen sensor tho as it shuts off on me while driving or sometimes coming to a stop. You might try checking the fuel filter and pump as well.
