Hello, I'm Jason. I will do my best to answer your question quickly and accurately using the information you have provided.
that means you have an ignition misfire in cylinder #4
there is a factory recall on the ignition coils, which will likely take care of this problem
you will need to call your local dealer with your VIN and schedule an appointment, and they will replace all 4 ignition coils at no cost
I also recommend not driving this car for more than 5-10 miles, as the unburned fuel could potentially harm your catalytic converter
