There may be an extended warranty on the ignition coils - see your  Ford Dealer for more information-Thanks John B for this information!

The valve cover gaskets may leak oil into the spark plug wells, shorting out the spark plugs, causing a misfire, and illuminating the Check Engine Light. Commonly the spark plugs and ignition coils or wires will require replacement, along with resealing the valve cover to correct this concern.
