I received a p0300 code : #4 cylinder misfire.
At highway speeds seems fine.
Up to 20 mph its rough after smooths out.
I have a new coil pack on order.
My question is will short drives (1 mile) to work be risky?

 

In addition found oil around #4 spark plug (above the head) as well as two or three other spark plug wells. There was not a lot of oil. I changed the coil bank on the radiator side and the car is idling much better. Maybe gaskets need replacing but hear its not easy. Any thoughts appreciated.
