What Causes Engine Shaking During the Break-in Period of a New Car?
1 Answers
During the break-in period of a new car, engine shaking can be caused by several factors: incorrect installation of the engine's rubber mounts, leading to distortion; excessive carbon buildup on the spark plugs, resulting in engine vibration; or the accumulation of deposits in the fuel system. Additionally, failure to perform timely maintenance, such as oil changes, during the break-in period can contribute to this issue. Extended Information: Solutions for Engine Shaking: 1. Clean Carbon Deposits Promptly: If the throttle body or fuel injectors are malfunctioning—such as a dirty throttle body or excessive carbon buildup on the injectors—gasoline may be absorbed by the deposits, making the vehicle hard to start. Regular cleaning of carbon deposits is essential to avoid unnecessary wear. 2. Inspect the Condition of Spark Plugs: Faulty spark plugs can disrupt the ignition system. Check for excessive carbon buildup and replace them if necessary. 3. Verify Fuel Pressure: Unstable fuel pump pressure can also cause engine shaking. Inspect the fuel pressure and replace any faulty components promptly.
