It coughs to start
The car has 17k miles and it happened last year when it had 5000 miles. When you first start it up, the rpm won't go right up all the way. It stops at 5 or 600 rpm for a second or two, then it seems misfiring to start up slowly. It seems that dealer even doesn't want to deal with this problem at all. Ever since i had the first problem, I felt that the engine has not been smoothly idling at P.
