What That Check Engine Light Might Be Telling You
That Light Isn’t Just a Glitch—It’s Your Car Asking for Help
We know how frustrating it is—you're driving through Merrick or stuck on Sunrise Highway and suddenly that little amber engine icon pops on. Your stomach sinks. Is it serious? Is it safe to keep driving?
We get it. It’s stressful. But here’s the truth: that check engine light is your car’s way of letting you know something isn’t right, and it’s time to take a closer look.
At Dr. Jack’s Auto Repair, we’ve been helping Long Island drivers figure out exactly what’s going on since 1976—and we’d like to help you too.
Common Reasons Your Check Engine Light May Be On
That light can mean a wide range of things. Some are minor, but others… not so much.
Here are a few common reasons we see all the time in our shop:
- Loose or damaged gas cap – Surprisingly, this is one of the most common culprits.
- Oxygen sensor failure – This can affect fuel economy and emissions.
- Catalytic converter issues – This is a critical (and expensive) part of your exhaust system.
- Spark plug or ignition coil problems – If your engine feels rough, this could be the cause.
- Mass airflow sensor issues – Impacts engine performance and fuel efficiency.
- Transmission trouble – Yes, your check engine light could be tied to shifting problems too.

You could try guessing what the problem is. You could even go to a chain store that gives you a generic code reading. But that usually leads to more confusion than answers.

Whether it’s a quick fix or something more involved, you’ll get a clear explanation, honest advice, and repairs you can trust.
