I was driving in highway traffic in the right hand lane at about 70-75 miles per hour. The weather was clear and the temperature was approximately 50 degrees. I encounter a slow moving vehicle and moved into the left hand lane and tried to promptly accelerate to pass a slower vehicle. When I attempted to accelerate the vehicle began to shake violently and go into a very rapid deceleration. The violent vibration of the entire vehicle and rapid deceleration made control a challenge. I moved to the right hand lane reduced speed to 50 mph and continued on to a Ford dealership to have the vehicle evaluated. The dealership found that 3 coils failed which caused the vehicle to vibrate and decelerate rapidly. I had the vehicle repaired.
