Your check engine light can come on due to many faults that can happen to your vehicle. From the engine, to the transmission to brake issues and electrical systems. If this happens and your engine is running rough then it could be due to a component within your ignition system that is causing the issue. You need to make it an appointment to have it diagnosed to make sure the correct component is being replaced. Give us a call and let us take care of you.
Happy Adventures,
