If it's not throwing codes and the idle is only slightly rough (a couple of misses here and there) It's probably fine. Mine does it too ever since I bought mine a year ago. Another one I test drove also did it. I think these cars are just tuned to the edge during cold start in order to meet emissions standards. Also, the injectors fire two pulses during cold start instead of one so I think that contributes to the slightly rough idle on cold starts. I could be wrong but I just feel if there are problems with our injectors it would show a code.
