Why is My Check Engine Light Flashing and Car Shaking – Causes
Modern cars contain a ton of dashboard lights to inform drivers about any possible damage in the vehicle. Each light represents a different problem which may lie in the engine, body or any other component. One of the dashboard lights is the engine check light.
There can be several reasons for engine check light blinking. Generally, it indicates a fault in the car’s engine or any possible misfire.

A Bad Fuel Injector
Fuel injectors are responsible for injecting fuel into the engine. A bad or faulty fuel injector may affect the fuel supply to the engine – resulting in a possible engine misfire and leading to a flashing engine check light.
The most common problems a fuel injector faces are blockage and leakage. In both scenarios, the fuel injector becomes ineffective and can lead to engine problems.
A Faulty Idle Air Control Valve
If you are wondering why is my check engine light flashing and car shaking, a faulty idle air control valve could be the reason behind it. Located on the throttle body of a petrol engine, an idle air control valve regulates the amount of air entering the engine.
Any faults in the idle air control valve can lead to irregular airflow inside the engine. This usually leads to a vehicle shaking and engine check light blinking.
A Blocked Fuel Filter
A fuel filter ensures a smooth fuel run to the engine. A bad or blocked fuel filter may cause the engine to misfire and lead to vehicle shaking. In the case of a blocked fuel filter, the engine fuel ratio is disturbed which prevents the engine from functioning properly.
Under such conditions, drivers may encounter acceleration issues along with car jolting and this may also trigger the transmission light.
A Damaged Ignition Coil
Ignition coils are responsible for powering the spark plugs. They do so by generating a high-voltage current that powers the plugs. A damaged ignition coil can be a reason for engine light flashing and vehicle shaking.
Some other common symptoms of a damaged ignition coil include decreased fuel economy, car hard to start, engine misfiring and a rough engine idle.
Faulty Engine Sensors
For people wanting to know why is my check engine light flashing and car shaking, faulty engine sensors can also be the reason behind these. Engine sensors are responsible for monitoring some major engine functions such as air pressure, fuel pressure, engine temperature, engine timing and engine oil pressure.
Any fault in these sensors can have dire effects on the car’s engine. With faulty sensors, drivers may experience issues like engine stalling, lack of power and poor fuel economy.
Damaged Spark Plugs
Spark plugs provide a spark to ignite air mixture and fuel inside a vehicle. A fault in any of the spark plugs leads to a possible cylinder misfire. If the issue is not fixed promptly, drivers may experience a shaking vehicle along with a flashing dashboard light.
