mass air flow sensor yes correct thank you

does this car have the fuel pressure regulator up on the fuel rail?... or in tank.....older 3.8 series II would randomly stall when fuel regulators would leak....

I had a 1997 Olds 88 that would start fine in the morning but after driving to my various service calls during the day it would not start in the afternoon. I would have to wait about 10 minutes and then it would start. I replaced the fuel pressure regulator and had no more starting issues.
