While driving at 65 - 70 mph on I-95, the spark plug on the #2 cylinder blew out. #2 cylinder is 2nd plug from front of engine on the passenger side. Loud noise and lost power.
As I was driving home, my engine began making a loud noise & running badly. Upon inspection of the motor, I found the spark plug had blown out of the #3 cylinder, breaking the coil pack in the process. I do not believe this is a normal occurance. I have checked on-line to see if this has happened to other F-150 owners, and found out it is fairly common. What can be done to get Ford to help with this problem?.
