360 Modena start-up

Hey everyone, I have a question about a noise my car makes when I start it up. It seems to cough or sputter for a 5-10 seconds before it finds its groove. I haven't had the car long enough to know if this is normal or if I should be concerned. Once it settles down the drive is perfect and there are no signs of trouble, but want to know if this early engine noise is a sign of a future problem. Thanks in advance for helping me out.
