If you are experiencing these symptoms, it is important to have your car inspected by a qualified mechanic as soon as possible to determine the cause of the problem and get it repaired.

1. Misfiring engine

A misfiring engine is a common cause of a car shaking and the engine light flashing. When an engine misfires, it means that one or more of the cylinders is not firing properly. This can be caused by a variety of factors, including faulty spark plugs, dirty or clogged fuel injectors, or a vacuum leak.

Ignition system problems: The ignition system is responsible for creating the spark that ignites the air-fuel mixture in the cylinders. If there is a problem with the ignition system, such as faulty spark plugs or wires, it can cause the engine to misfire.
Fuel system problems: The fuel system is responsible for delivering fuel to the cylinders. If there is a problem with the fuel system, such as dirty or clogged fuel injectors, it can cause the engine to misfire.
Air intake system problems: The air intake system is responsible for delivering air to the cylinders. If there is a problem with the air intake system, such as a vacuum leak, it can cause the engine to misfire.
Mechanical problems: In some cases, a misfiring engine can be caused by mechanical problems, such as a worn or damaged piston ring.

If you are experiencing a misfiring engine, it is important to have your car inspected by a qualified mechanic as soon as possible. A misfiring engine can damage your car's catalytic converter and other components, and it can also make your car unsafe to drive.

2. Problem with the transmission

A problem with the transmission can also cause a car to shake and the engine light to flash. The transmission is responsible for transferring power from the engine to the wheels. If there is a problem with the transmission, it can cause the car to shake or vibrate. In some cases, a problem with the transmission can also cause the engine light to flash.

Slipping transmission: A slipping transmission is a common problem that can cause a car to shake and the engine light to flash. When a transmission slips, it means that it is not able to properly transfer power from the engine to the wheels. This can cause the car to shake or vibrate, and it can also cause the engine light to flash.
Faulty torque converter: The torque converter is a component of the transmission that helps to transfer power from the engine to the transmission. If the torque converter is faulty, it can cause the car to shake and the engine light to flash.
Damaged transmission gears: Damaged transmission gears can also cause a car to shake and the engine light to flash. Transmission gears are responsible for transferring power from the engine to the wheels. If the gears are damaged, it can cause the car to shake or vibrate, and it can also cause the engine light to flash.
Low transmission fluid: Low transmission fluid can also cause a car to shake and the engine light to flash. Transmission fluid is responsible for lubricating the transmission and keeping it cool. If the transmission fluid is low, it can cause the transmission to overheat and malfunction. This can cause the car to shake or vibrate, and it can also cause the engine light to flash.

If you are experiencing a problem with the transmission, it is important to have your car inspected by a qualified mechanic as soon as possible. A problem with the transmission can damage your car's engine and other components, and it can also make your car unsafe to drive.

3. Faulty suspension system

A faulty suspension system can also cause a car to shake and the engine light to flash. The suspension system is responsible for absorbing shocks and vibrations from the road, and for keeping the car's wheels in contact with the road. If the suspension system is faulty, it can cause the car to shake or vibrate, and it can also cause the engine light to flash.

Worn or damaged shocks or struts: Shocks and struts are components of the suspension system that help to absorb shocks and vibrations from the road. If the shocks or struts are worn or damaged, they can cause the car to shake or vibrate, and they can also cause the engine light to flash.
Broken or damaged springs: Springs are components of the suspension system that help to keep the car's wheels in contact with the road. If the springs are broken or damaged, it can cause the car to shake or vibrate, and it can also cause the engine light to flash.
Loose or damaged control arms: Control arms are components of the suspension system that help to keep the car's wheels aligned. If the control arms are loose or damaged, it can cause the car to shake or vibrate, and it can also cause the engine light to flash.
Faulty sway bar: The sway bar is a component of the suspension system that helps to reduce body roll when the car is cornering. If the sway bar is faulty, it can cause the car to shake or vibrate, and it can also cause the engine light to flash.

If you are experiencing a problem with the suspension system, it is important to have your car inspected by a qualified mechanic as soon as possible. A faulty suspension system can damage your car's tires and other components, and it can also make your car unsafe to drive.

4. Loose or damaged spark plugs

Loose or damaged spark plugs can cause a car to shake and the engine light to flash. Spark plugs are responsible for creating the spark that ignites the air-fuel mixture in the cylinders. If the spark plugs are loose or damaged, they may not be able to create a strong enough spark, which can cause the engine to misfire.

A misfiring engine can cause a car to shake and vibrate. It can also cause the engine light to flash. In some cases, a misfiring engine can also damage the catalytic converter and other components of the exhaust system.

It is important to have your spark plugs inspected and replaced regularly. This will help to ensure that your engine is running properly and that you are getting the best possible fuel economy.

5. Dirty or clogged fuel injectors

Dirty or clogged fuel injectors are a common cause of a car shaking and the engine light flashing. Fuel injectors are responsible for spraying fuel into the cylinders of the engine. If the fuel injectors are dirty or clogged, they may not be able to spray fuel properly, which can cause the engine to misfire.

It is important to have your fuel injectors cleaned or replaced regularly. This will help to ensure that your engine is running properly and that you are getting the best possible fuel economy.

6. Vacuum leak

A vacuum leak is a common problem that can cause a car to shake and the engine light to flash. A vacuum leak occurs when there is a hole or crack in the intake manifold, which is the part of the engine that mixes air and fuel. When there is a vacuum leak, air is able to enter the engine without being metered by the mass airflow sensor. This can cause the engine to run lean, which means that there is not enough fuel in the air-fuel mixture. A lean engine can cause a car to shake and vibrate, and it can also cause the engine light to flash.

In addition to causing a car to shake and the engine light to flash, a vacuum leak can also lead to other problems, such as:

Decreased engine power
Increased fuel consumption
Rough idle
Stalling

If you think your car may have a vacuum leak, it is important to have it inspected by a qualified mechanic as soon as possible. A vacuum leak can damage your car's engine and other components, and it can also make your car unsafe to drive.
