Why is your 2001 subaru outback shaking and stuttering with the check engine light blinking?

Your 2001 Subaru Outback is likely experiencing engine misfires, which can cause shaking and stuttering, especially if the check engine light is blinking. This could be due to issues such as faulty spark plugs, ignition coils, or fuel delivery problems. A blinking check engine light indicates a serious issue that could damage the catalytic converter, so it's important to diagnose and address the problem promptly, ideally with a diagnostic scan tool or by visiting a mechanic.
