As I was merging onto the freeway, I heard a loud bang followed by a motorcycle sound out of my engine my check engine light came on, upon taking it to the shop and paying $94. 50 just to look at it,I learned that my spark plug and coil box had exploded out. . . . . . The repair place told me this is a on going problem with Fords and charged me $400 to fix it. . . This should be a recall??????.
