A car shakes when starting up cold because the engine is not as lubricated as when it’s warm, causing friction and vibrations. This can be due to a lack of air or faulty spark plugs.
Snow or slush build-up on wheels that freeze after parking can also cause shaking. Additionally, flat-spotted tires from sitting overnight can contribute to the issue. If the shaking persists after the engine warms up, it could indicate a fuel delivery problem.
It’s recommended to replace spark plugs and wires, check plug wells for cleanliness, and ensure tires are properly inflated.

Why Car Shakes When Starting Up Cold
When the engine is cold, it’s not as lubricated as when it’s warm, so the parts of the engine rub against each other more than usual. This friction causes vibrations and noises that you don’t hear when the engine is warm.
A shaking or juddering feeling when you start your car can be caused by problems with your engine due to a lack of air or faulty spark plugs. Checking and replacing the spark plugs and wires, as well as ensuring the plug wells are clean and dry, can help address this issue.
Cold weather can also contribute to car shaking. Snow and slush buildup on wheels while driving can freeze after parking, causing vibrations. Additionally, the cold weather can affect rubber components and cause increased friction and vibration when starting the engine.

Frequently Asked Questions For Car Shakes When Starting Up Cold
Why Does My Car Shake A Bit On Cold Start?
When your car shakes a bit on cold start, it’s because the engine isn’t as lubricated as when it’s warm. This causes friction between the engine parts, resulting in vibrations and noises that are more noticeable when the engine is cold.
Why Is My Car Shaking As Soon As I Start It?
Your car may shake when you start it because the engine is cold and not properly lubricated. This causes increased friction and vibrations between engine components. Additionally, faulty spark plugs or a lack of air can also contribute to the shaking.
Consider replacing spark plugs or consulting a mechanic if the problem persists.
Why Does My Car Shake Until It Warms Up?
When your car shakes until it warms up, it’s usually because the engine isn’t lubricated enough when cold. This causes increased friction between engine parts, leading to vibrations and noises. It can also be a result of flat-spotted tires. To address this issue, consider replacing spark plugs and wires, and check that the tires are properly inflated.
Can Cold Weather Cause Car To Shake?
Cold weather can cause a car to shake on startup. When the engine is cold, parts rub against each other more than usual due to lack of lubrication. This friction causes vibrations and noises that you don’t hear when the engine is warm.
Conclusion
When your car shakes on cold start, it’s due to the lack of lubrication in the engine. As a result, the engine parts rub against each other, causing vibrations and noises. This is a common issue during cold weather. To resolve this, consider replacing spark plugs and wires and ensure the tires are not flat-spotted.
Remember, regular maintenance and warm-up can help prevent this shaking. Take care of your car, and it will run smoothly even during those chilly mornings.
