The dreaded check engine light. It always seems to appear at the worst time—and it’s never clear what it means without a diagnostic test. It could be a loose gas cap... or it could be a failing catalytic converter or engine misfire.
So what do you do when your check engine light is on? Should you fix it—or is it better to sell the car as-is and move on?
Let’s break down what that light really means, what it might cost to fix, and when it’s smarter to skip repairs altogether and sell your car with the check engine light on.
