For example, does it happen when you accelerating, driving on the highway or does it appear at low speeds? This will help your mechanic evaluate the issue. Steady Check Engine Light: If your check engine light is on every time you operate your Focus, you need to have it checked as soon as possible, especially if you notice performance problems or unusual noises.
