When turning car on it the engine makes a knocking sound. Car is losing acceleration on roads especially expressway. Also, the engine pings or knocks when turning the car off. I have even heard the engine knock while in motion. The front windshield molding garnish lh located on the driver side flew off while driving on the expressway and hit another car! losing this molding garnish causes air to leak into the windshield.
