“I own a 2001 Lincoln Navigator with a 5.4l engine. I was on my way to work and was going approx. 15 MPH when I heard a bang coming from the front of the car. At first I thought I had hit something or something was falling off the car. I pulled over to the side of the road and at this time the engine started to run rough. I shut it off and checked under the hood but could not see anything wrong. I thought, after restarting the engine that it might be a bad spark plug. …”
