Check Engine and Car Shaking: Causes and Solutions

What Causes a Check Engine Light to Come On?

There are many different reasons why a check engine light might come on. Some of the most common include:

Emission control system malfunctions: This is the most common cause of a check engine light. When the emission control system is not working properly, it can cause the engine to run inefficiently and pollute the environment.
Oxygen sensor problems: Oxygen sensors are used to monitor the amount of oxygen in the exhaust. If the oxygen sensors are not working properly, it can cause the engine to run rich or lean, which can lead to a check engine light.
Spark plug or ignition coil problems: Spark plugs and ignition coils are used to ignite the fuel in the engine. If these components are not working properly, it can cause the engine to misfire, which can lead to a check engine light.
Vacuum leaks: Vacuum leaks can occur when there is a hole or crack in a vacuum hose or line. This can cause the engine to run lean, which can lead to a check engine light.

What Causes Car Shaking?

Car shaking can be caused by a variety of factors, including:

Unbalanced tires: Unbalanced tires can cause the steering wheel to shake when driving.
Worn suspension components: Worn suspension components, such as shock absorbers or struts, can cause the car to shake when driving over bumps or potholes.
Brake problems: Brake problems, such as warped brake rotors or worn brake pads, can cause the car to shake when braking.
Driveline problems: Driveline problems, such as a worn universal joint or a bent driveshaft, can cause the car to shake when accelerating or decelerating.

How to Fix a Check Engine Light and Car Shaking

The best way to fix a check engine light and car shaking is to take the car to a qualified mechanic. The mechanic will be able to diagnose the problem and recommend the best course of action. In some cases, the mechanic may be able to fix the problem by replacing a faulty part or repairing a leak. In other cases, the mechanic may need to perform a more extensive repair, such as replacing the entire emission control system.

Preventing Check Engine Lights and Car Shaking
