What Is Your Check Engine Light Telling You? Our Fremont Mechanics Can Help

If your car's check engine light flickers on, it's a clear sign that something might be wrong under the hood. While it’s tempting to ignore a brief warning, paying attention to this light can save you from costly repairs down the line. We discuss some common signs that your car needs engine repair and why it’s important to address them promptly. When your car needs a check engine light diagnosis and repairs, contact ASAP Automotive in Fremont, CA.
Unusual Engine Performance
If you notice your car hesitating when accelerating, stalling unexpectedly, or even experiencing a rough idle, these could be early indicators that something within the engine or fuel system isn’t functioning properly. A misfiring engine, for example, may trigger the check engine light, pointing to issues with spark plugs, ignition coils, or fuel injectors.
Decrease in Fuel Efficiency
Another telltale sign is a sudden drop in fuel economy. When your engine isn’t running optimally, it tends to burn more fuel. If you find yourself making extra trips to the gas station without a clear reason, it could be due to an underlying problem that your check engine light is trying to warn you about.
Strange Noises or Vibrations
Unusual sounds—such as knocking, rumbling, or even high-pitched whines—often accompany engine troubles. Vibrations that weren’t there before, especially at idle or when accelerating, may signal that your engine’s internal components are under stress. These issues can contribute to long-term damage if left unchecked.
Odors and Exhaust Changes
A noticeable change in exhaust odor, such as a burning smell or the appearance of excessive smoke, can also indicate problems. These symptoms might suggest issues like a malfunctioning catalytic converter or an oil leak, both of which can affect your car’s emissions and performance.
What to Do Next
If your check engine light is on or you’re experiencing any of these symptoms, schedule an appointment with a trusted mechanic as soon as possible. The mechanics at ASAP Automotive can run a diagnostic test to pinpoint the issue and recommend the necessary repairs. Ignoring the light or postponing repairs can lead to more severe damage, reducing your car’s performance and potentially leaving you stranded.
