My Check Engine Light Just Came On? What Do I Do?

First off, stay calm. The check engine light is very annoying. It gives you just enough information to worry you, but without a diagnostic tool like an auto mechanic would have, you would be playing a guessing game. If your check engine light is lit up, though, whatever the reason, it means that you have problems somewhere in your emissions system.
The list of things that can trigger the check engine light is kind of long. A loose gas cap can cause it, which is an easy fix, all the way to the worst problem: a blown cylinder gasket. As to what you do, first off, check to see if your gas cap is on tight. If so, then you have to get into an auto mechanic.
Can’t I Let My Check Engine Go?
We don’t recommend it. Covering it up or unplugging the light and pretending there’s not problem has never worked. Then the problem gets worse as a rule. And as we said, one of the causes of a check engine light is a blown cylinder head gasket, and that can lead to a cracked engine block. Your car is a very expensive paperweight then. Most people can’t afford a brand new engine.
Remember, problems are best dealt with as soon as they come up, or even better, before they come up. So, if your check engine light comes on, get it into a mechanic immediately. And you want to make sure that any mechanic you go to can handle an emissions system repair.
