2007 Ford F-150 electrical system problems

I was involved in a motor vehicle accident in which my airbag deployed at which time, and although I had slammed on my brake, my trucks accelerator stuck causing my truck to proceed at an accelerated speed pushing the car I had just hit and veering off the road and hitting some trees and brush. I slammed on my brake once again stopping the truck.

Tl* the contact owns a 2007 ford f-150. While driving approximately 15 MPH, the check engine warning indicator illuminated and the vehicle started to lose acceleration and power. The contact had to pull into a fuel station. The mechanic at the station determined that the ignition coil and a spark plug failed and needed to be changed. The vehicle was repaired. The failure recurred three other times and was repaired. The manufacturer was notified of the failure. The VIN was invalid.
