You can drive quite a long time when the check engine light comes on and sometimes the check engine light being on can be caused by something as simple as the gas cap not being on tight enough.

But other times the check engine light could be coming on to alert you to something else such as bad spark plugs, bad ignition coils, bad spark plug wires and other engine misfires.

If your check engine light is coming on then you should have the check engine light tested at places such as Autozone or oreillyauto and they will check it for free and let you know what kind of problem you're having.

So I would drive to the auto parts store and have them check the check engine light to see what is going on with the vehicle.

They can tell what part is causing the problem and if you need that part you can buy it there if you have the money.
