I was pulling off from a stop sign and before I got across the intersection my car make a pop and then the engine sounded like it blew. I pulled over and a spark plug popped out of the head causing a small fire that melted hoses. Estimated damage is a minimum of 1500 for just this plug but I was told the others would follow suit. Reading on the internet this seems to be a serious issue with the Ford 5. 4 triton motors. If I was not able to stay calm and steer my vehicle correctly this could have resulted in a serious accident. The vehicle lost power as if it had stalled, and as I stated before there was a small fire when I lifted the hood to see what had happened.
Gas mileage 6 mpg city and 11 mpg highway. Power windows make a loud scratching sound when operated.
