My little spot on the Internet about tune up
What could be wrong? A flashing checking engine light is frustrating as the check engine light could signal a number of different issues. When your car is running correctly, your engine light should illuminate only when you switch on your ignition. When your engine light either remains illuminated or suddenly goes on while you are driving, it usually indicates an issue with the engine management system. Get in to a certified technician as soon as possible. Get your check engine light checked if it abruptly starts flashing while you are driving.
