Still on our way home from the rally. Pulled out of the camp ground in Texas and the service engine soon light came on and starting blinking. Set my scan gauge to scan, and got subject code. #6 cyl bad spark or coil. Headed to the next town with an orileys and a camp ground. Took the little smart and got a new coil pack and a plug. A motor craft coil pack was $79.99!, ( each x 10 )went with the house brand. Out of all the plugs, this was probably the easiest to get to after removing the air cleaner. Took about an hour and all is well. This is a 2013 with only 30k miles.
