Check Engine Light Flashing and Car Vibrating: Causes and Solutions

Causes of a Flashing Check Engine Light and Car Vibration

There are several potential causes of a flashing check engine light and car vibration. Some of the most common include:

Misfiring engine: A misfiring engine can cause the car to vibrate and the check engine light to flash. This is often caused by a faulty spark plug or ignition coil.
Fuel injector problems: A clogged or faulty fuel injector can cause the car to run lean or rich, which can lead to engine vibration and a flashing check engine light.
Transmission problems: A problem with the transmission, such as a slipping clutch or a faulty torque converter, can also cause the car to vibrate and the check engine light to flash.
Vacuum leak: A vacuum leak can cause the car to run lean, which can lead to engine vibration and a flashing check engine light.
Loose spark plugs: Loose spark plugs can cause the car to misfire, which can lead to engine vibration and a flashing check engine light.

What to Do If Your Check Engine Light Is Flashing and Your Car Is Vibrating

If you’re experiencing a flashing check engine light and car vibration, it’s important to take the following steps:

Pull over to a safe location: If you can, pull over to a safe location as soon as possible. This will help prevent further damage to your car.
Turn off the engine: Turn off the engine and allow it to cool down for a few minutes.
Check the oil level: Check the oil level and add oil if necessary. A low oil level can cause engine damage.

Have the car towed: If you’re not able to fix the problem yourself, have the car towed to a mechanic.
