Check Engine Light

There are countless reasons your check engine light (CEL) might be lit up, and even if you know the specific code it might not provide you with much in the way of a diagnosis. Bringing your vehicle to a professional for an in-depth inspection and diagnosis is your best bet for avoiding the issue worsening and becoming more problematic. 

Some common causes of check engine lights include:

• Faulty spark plugs 
• Faulty/dirty mass airflow sensor
• Issues with catalytic converters
• Internal engine issues
• Damaged or faulty oxygen sensors

You should always bring in your car as soon as you see the dreaded orange light, but if the light is flashing, it’s imperative you do not continue driving the vehicle. A flashing CEL indicates a misfire, and continuing to operate the vehicle can lead to expensive or even catastrophic engine issues. 

That being said, CELs can often be something simple, such as a loose gas cap. It’s better to be safe than sorry though, and bringing in your vehicle is your best bet to avoid further issues.
