The diagnostic scanner said I need a tune up. How do I replace the spark plugs? There is an ignition coil on each spark plug.

Remove the coil on top of each plug, then the plug is replaced normally, just like any other.
It sounds like you have an engine misfire, and the codes you retrieved are P0300 codes? If that's the case, read this before attempting to fix this. http://repairpal.com/OBD-II-Code-P0300
