Don’t Know Why Your Check Engine Light is On?

What Is Causing My Car to Shake with the Check Engine Light On?

Whenever the check engine light pops up on your dashboard, you may experience a sinking feeling in your stomach. While the culprit behind that bothersome light could be something as simple as a loose gas cap, an illuminated check engine light is always stressful.

But what if your car starts shaking too? The ASE-certified mechanics at First Tire & Automotive in First Colony – Sugar Land, Texas, are here to put your mind at ease.

Here’s everything you should know about why your vehicle is shaking with the check engine light on.

Engine Misfires Are to Blame

The most common reason for your car to be shaking with its check engine light on is because of engine misfires. To put it simply, your check engine light will be triggered if there’s a problem that increases your car’s emissions.

An engine misfire happens when incomplete – or no – combustions occur inside one of the engine cylinders. If the misfire is powerful enough, your car could start to shake. Misfires typically happen when the engine lacks a precise fuel-air combination, a good compression, or an adequate spark.

What Causes an Engine Misfire?

There are several things that will cause your engine to misfire, including:

  • Air-fuel mixture problems, including a damaged fuel injector
  • Ignition system issues, such as a worn-out spark plug
  • Mechanical problems
  • Faulty wiring
  • Failing sensors, like a broken mass airflow sensor
  • Computer issues, including software that needs to be updated

To pinpoint the exact cause of your engine misfire, it’s essential to book a check engine light service appointment at a reputable auto repair shop.

Is It Safe to Drive My Shaky Vehicle?

If your car is shaking because of an engine misfire, do not attempt to drive. This could lead to bigger damages and is also extremely unsafe. It’s always better to call a tow.
