What is the reason for car shaking during acceleration but stopping when releasing the throttle?
2 Answers
The reasons for car shaking during acceleration but stopping when releasing the throttle are: 1. Excessive carbon deposits and low fuel pressure, leading to insufficient fuel supply and power output. It is recommended to clean the fuel injectors and check the fuel pressure; 2. Poor ignition causing incomplete combustion, along with noticeably higher fuel consumption. It is recommended to replace the spark plugs; 3. Insufficient cylinder compression, which requires a cylinder compression test. Methods to reduce carbon deposits in cars include: 1. Performing regular car maintenance and changing the engine oil; 2. Cleaning the car's air filter; 3. Regularly replacing the car's spark plugs; 4. Cleaning the car's throttle body; 5. Avoiding sudden acceleration and minimizing hard braking; 6. Regularly replacing the car's fuel filter.
As a frequent driver, when my car shakes during acceleration but stops when I release the throttle, this issue is often related to the ignition system. Worn-out spark plugs or carbon buildup can cause poor ignition, leading to shaking when the engine load increases during acceleration. Insufficient fuel pump pressure can also result in unstable fuel supply. For manual transmission cars, worn clutch plates can cause shaking when power delivery is inconsistent during acceleration. While unbalanced tires have a greater impact at high speeds, acceleration shaking is usually related to the engine. It's a good practice to check the spark plugs' lifespan during regular oil changes—prevention is better than repair. Long-term neglect may damage more components and increase repair costs. I recommend visiting a professional shop for diagnosis as soon as possible. Don't underestimate such minor shaking—it often indicates bigger issues.
