4cyl engine sputter

The last few mornings when i start my truck i have noticed that, while the engine is cold, the first one or two times i try to accelerate the engine will sputter like its bogging down or running out of gas. When i ease off the accelerator then accelerate again it will accelerate just fine. Once i get going and the motors starts to warm up it will run just fine. I live in south louisiana so it sure as hell isnt cold here and i have not done anything to the motor lately besides change my battery a month ago. Any suggestions?

 

my dads v6 did that and he got a tune up and now it runs fine
