1998 Plymouth Breeze sputtering at aidle for about three mi

So I have a 1998 plymouth breeze that has had an overhaul done on the engine at about seventy thousand because the person I bought it froms daughter blew it up or something not important. But just recentley I have had some problems with it at starting point, what happens is if I do not let it warm up then it kinda bogs down when I push on the accelerator, it has to sit for about three minuets it then runs perfect. What I need to know is why this is happening when I start it, it does it everytime you shut it off and restart it even if its just for a second or two, and its not because its cold cus its hot as hell weather wise right now so what is the issue thanks.
