engine start-up issue

[AudiloverS4]

So yesterday night i start my car and throw it into reverse at which point the engine begins to run a bit rough and the check engine light flashes a few times. When the light stops flashing the engine is still running rough and the car is just creeping backward. I restarted the car and everything was back to normal, no problems today. Has anyone had this issue before? I've got about a month left on the warranty so i want to catch this if its a potential problem.

Thanks in advance guys. (and gals)

I have no idea, but if you are still under warranty I would take it in ASAP and let them check it out.
