Cool engine trouble 1997 buick lesaber

Hello,
I am having trouble with my car, here is what is happening, when I first start up the car it sputters and seems to struggle to acelerate, when the car warms up this goes away for the most part. It only does it occationally when acelerating or when going up a steep grade and the engine has to labor harder. I have changed the fuel filter, this doesn't seem to make any difference. Any suggestions would be a great help!!

O by the way my car is a 1997 buick LeSabre it has a 3800 v6,

if it has not been tuned up or has the original plug wires you might start there.
you can also check the maf senor and clean it if needed believe its on the throotle body has 3 screws holding it on just remove sensor and spray with carb cleaner if it has any build up on the 2 heated wires.

Pull the vacuum line off the fuel pressure regulator and see if there is any moisture (gas) inside the line or leaking out of the regulator.
