Rough idle noticed while stopped at an intersection. Catastrophic misfire upon acceleration through an intersection. Truck was only able to "limp" 5 or less miles per hour. Check engine light had been turning off and on however diagnostics showed misfire for unknown reasons. Spark plugs and wires had been replaced twice within a year as well. Defected head manufactured by Ford.

The first incident occurred on 12/15/2011 as I was traveling from savannah, ga. To atlanta, ga. I was getting off my exit to the I675 and slowed down by hitting the brake and the vehicle started to speed up. I was not using the speed control at all as I missed my exit and shut the vehicle off in order to stop. On 12/22/2011 I was coming home to detroit, mi. And had an accident in ga. I was traveling at 35 mph, it was raining heavily and as I proceeded to slow down around a curve I immediately lost control of vehicle as the truck fishtailed into oncoming traffic and I turned my wheel to avoid a collision with 2 vehicles in that lane and ended up in a culvert.I sustained minor injuries but luckily there were no other injuries or deaths as this vehicle was the only one involved. At that time I did not put 2 and 2 together as I thought the road was slippery and I couldn't avoid what had happened. On 12/24/2011, I visited my family in rochester, mi. And went to slow down at a light and the vehicle began speeding up again causing me to go through the light and I turned the engine off because I could not stop the vehicle and I realized the peddle was to the floor. Luckily I was driving this vehicle instead of my sister who actually owns this. This is my first accident since I have gotten my license back in 1968 and it could have been a lot worse. At no time was I using the speed control.

Run away engine after using cruise control. The cruise control has not functioned for the last 1.5 yrs. The on light will come on but it won't set. It went out, but after it stopped working the engine accelerated briefly without the cruise control activated but we had pushed the on button to see if it worked. This also occurred a second time after turning the cruise control on and of. The first two episodes weren't too bad and the vehicle RPM slowed down after the brakes were applied. Just this last week I tried the cruise control again to see if it would work and it didn't. aprox two days later while coming to a stop and not using the cruise control the engine raced while approaching a stop light. I had to stand on the brakes to keep from going thru the light. I finally placed the transmission in neutral and the engine was still racing. This ended after a few seconds. I was standing on the brakes the whole time. Let me be clear, this has happened three times with the last time 1.5 years ago being the worst. It started occurring after the cruise control wouldn't turn on and then one day suddenly did after hitting the button. Each instance occurred a few days after trying to get the cruise control to work. All three episodes occurred without ever touching the cruise control during the day that the engine racing occurred.

I was pulling into sherry's MINImart in doe run, mo when I realized that my truck was not slowing down as expected, even though I had my foot on the brake. I had little time to react as I was bearing down on the building. I put my other foot on the brake but the truck continued to move forward, even spinning the tires trying to overcome the brakes. I jumped the curb and hit the building at a very low speed. At this time I managed to pop it out of gear. I did not go through the wall, but pushed it in about a foot. My airbags did not deploy. Most of the damage was to the wall and the interior of the building. There was little damage to my truck other than a few scratches on the bumper. Luckily no one was walking in front of me or near the inside of the building. This was the only time this has occurred in the 50,000 miles that I have owned this truck and it has not happened in the days following. I took my truck to my Ford dealer the next morning and they claim they could find nothing wrong. They could find no fault codes in the computer and confirmed that there was no damage other than the scratches on the bumper. They did imply that I was hitting the accelerator pedal with the side of my foot while braking. I strongly disagree with their implication and have witnesses who saw my efforts to stop the truck.
