When the check engine light comes on in your Chevy Equinox, it's important to pull over and stop driving right away. Continuing to drive with the light on could potentially lead to further damage to your engine if there are any issues. Once you've safely stopped, you can use an OBD II scan tool on your car to identify the problem. If you receive a code P0300, it indicates that there was a misfire detected in the engine, which could be due to various factors like low-quality fuel, spark plug issues, or problems with the air intake. To pinpoint the exact cause, it's advisable to also check the ECU for any additional codes.
