Car Shaking When Turning On: Causes, Solutions, and FAQs

Have you ever experienced your car shaking when turning it on? This can be a cause for concern, as it could indicate a potential problem with your vehicle. In this article, we will explore the various causes of car shaking when turning on and provide possible solutions to address these issues. Additionally, we have included a frequently asked questions section to help answer any queries you may have.

Causes of Car Shaking When Turning On:

1. Engine Misfire: One common cause of car shaking when turning on is an engine misfire. This occurs when the fuel in the engine does not ignite properly, resulting in a rough running engine. The shaking is usually felt throughout the vehicle and can be accompanied by a check engine light.

2. Faulty Spark Plugs: Spark plugs play a crucial role in igniting the fuel mixture in the engine. If they become worn or damaged, they may not provide the necessary spark, leading to engine misfires and shaking.

3. Dirty Fuel Injectors: Over time, fuel injectors can become clogged with dirt, debris, or carbon buildup. This can disrupt the fuel delivery process, causing the engine to shake when starting.

4. Low Fuel Pressure: Insufficient fuel pressure can also contribute to a shaky start. This may be caused by a faulty fuel pump or a clogged fuel filter, preventing the engine from receiving the required amount of fuel.

5. Faulty Ignition Coil: The ignition coil is responsible for supplying the spark to ignite the fuel in each cylinder. If it malfunctions, it can lead to engine misfires and shaking.

2. Fuel Additives: Using fuel additives periodically can help clean fuel injectors and remove carbon buildup, improving engine performance and reducing shaking.

3. Ignition Coil Replacement: If the ignition coil is faulty, it may need to be replaced by a professional mechanic. Regular inspections and replacements, if necessary, can help prevent engine misfires and shaking.

4. Fuel System Inspection: If low fuel pressure is suspected, a thorough inspection of the fuel system is necessary. This may involve checking the fuel pump, fuel filter, and fuel lines for any clogs or malfunctions.


Q: Is it dangerous to drive when my car is shaking when turning on?

A: It is not advisable to drive a vehicle that is experiencing shaking when turning on. This indicates a potential issue that could lead to further damage or safety concerns. It is best to have a professional mechanic inspect and diagnose the problem before continuing to drive the vehicle.

Q: Can cold weather cause my car to shake when starting?

A: Yes, cold weather can contribute to car shaking when turning on. In colder temperatures, the engine oil becomes thicker, making it harder for the engine to start smoothly. This can result in shaking or rough running until the engine warms up.

Q: Why does my car only shake when turning on and not during normal driving?

A: Shaking that occurs only during start-up can be indicative of specific issues such as engine misfires or faulty spark plugs. During normal driving, the engine may run more smoothly once it has warmed up. However, it is still recommended to have the problem diagnosed and resolved to prevent further complications.

In conclusion, car shaking when turning on can be caused by various factors such as engine misfires, faulty spark plugs, dirty fuel injectors, low fuel pressure, or a faulty ignition coil. Regular maintenance, including spark plug replacement, fuel injector cleaning, and fuel system inspections, can help prevent these issues. If you experience shaking when turning on your car, it is crucial to have it inspected by a professional mechanic to address the problem promptly and ensure your safety on the road.
