Just heard from my mechanic (whom I've used for over 15 years and trust immensely) that the reason for the check engine light is that my 2012 F150 EcoBoost needs a new coil pack on one side. My truck only has 59,600 miles!!! Is this normal? Should I go to the Ford dealership and get a second opinion? My truck, of course, is no longer under warranty.

Thanks

 

More likely it needs fresh plugs - they are HELL on plugs. Sp-534's.

Post the code. Move the COP to another cylinder. If the code moves it's the COP. If not, it's the plug ( or something else).
