Check Engine Light Blinking and Car Shaking

Introduction

When your check engine light starts blinking, it’s never a good sign. It usually means that something is seriously wrong with your car, and you should take it to a mechanic as soon as possible.

One of the most common reasons for a blinking check engine light is a misfire. This means that one or more of your cylinders is not firing properly, which can cause your car to shake. Other symptoms of a misfire include rough idling, loss of power, and decreased fuel economy.

Another possible cause of a blinking check engine light and car shaking is a problem with your ignition system. This could be a faulty spark plug, ignition coil, or distributor. Ignition problems can also cause your car to stall or hesitate when you’re driving.

If you’re experiencing a blinking check engine light and car shaking, it’s important to have your car diagnosed by a mechanic as soon as possible. Ignoring the problem could lead to further damage to your car, and it could even be dangerous to drive.

What to Do If Your Check Engine Light Is Blinking and Your Car Is Shaking

1. Pull over to a safe location as soon as possible.
2. Turn off your engine.
3. Call a mechanic or have your car towed to a repair shop.

Do not continue to drive your car if the check engine light is blinking and your car is shaking. This could cause further damage to your car, and it could even be dangerous to drive.
