While driving on the highway at approximately 70 MPH my wife's 2009 honda odyssey began to shake as I stepped on the gas the engine light came on and the vehicle lost engine power and I had to manually steer to the side of the highway.. Upon opening the hood I could smell that something was burning. The vehicle was towed 79 miles to my mechanic. I was informed that a spark plug blew out completely and a portion of that plug entered the cylinder and damaged the engine.
