what does it mean if the ecm check engine light is on
If you're like most car owners, you have little idea about what that light is trying to tell you or exactly how you should react. Call it the most misunderstood indicator on your dashboard, the check engine light can mean many different things, from a loose gas cap to a seriously misfiring engine. It doesn't mean you have to pull the car over to the side of the road and call a tow truck.
