Why Is My Check Engine Light Flashing And Car Shaking

There are many causes of check engine light flashing and car shaking, and here are the most common reasons:

Spark plug has an error

The spark plug plays an essential role in the engine. This part helps to ignite and transmit fuel to other components inside the machine. From there, the car can operate normally.

However, one or more spark plugs that fail to generate sparks will stop the vehicle. Continuous sparking or no ignition will cause the car to vibrate, and the engines will alert the system to warn you.

In addition, spark plugs can also encounter corrosion when used for a long time. Since this part operates in harsh environments, it needs to be checked and changed regularly to produce a good performance.

Ignition ring not working

The ignition ring is the support for the spark plug that generates the spark. Basically, this part is like a mini transformer generating currents and transmitting power to the spark plug. Thanks to that, the spark plug can ignite and keep the vehicles running.

Using lousy ignition rings can cause the engine inside to make loud noises, and the car will vibrate abnormally. More dangerous, if you try to start the engine without checking, it will cause the car to stall completely.

Usually, when the ignition rings fail, they will not show any outward signs that the engines will have reduced performance in the long run, and the car will not be able to start.

Fuel filter clogged

But if this part fails, the performance of the engines will decrease, the fuel will be consumed significantly, leading to the car becoming shaken and the signal lights on.
