You report that the engine sputtered and ran badly when it was first started. At that point there could have been misfiring which later became normal. As a result a misfiring would have been recorded in memory to be disclosed later.
The actual cause will be difficult to pin point. Nothing indicates that you should be scared, much less overly concerned.
