If you notice the engine shaking intermittently, it may indicate the following potential issues with the vehicle: 1. Ignition system problems: Check the working condition of spark plugs, high-voltage wires, and ignition coils. Poor performance of the ignition system or suboptimal spark plug firing can lead to such symptoms. 2. Severe engine carbon buildup: The most common cause of vehicle shaking is excessive dirt on the throttle body or carbon deposits in the fuel injectors. 3. Unstable fuel pressure: It is recommended to visit a 4S shop to check whether the fuel supply pressure and intake pressure sensor are functioning normally. Abnormal fuel pump pressure or incorrect readings/malfunction of the intake pressure sensor can cause body vibration.

Is an Idle Speed of 600 RPM Normal?

An idle speed of 600 RPM is normal for a car. Here is some information about car engine idle speed: 1. Introduction: Car engine idle is one of the engine operating conditions, so the idle performance has a significant impact on emissions, fuel consumption, and comfort. The engine speed at idle is called the idle speed, which should not be too high or too low. If it's too high, it will increase fuel consumption; if it's too low, it will cause unstable idle speed. 2. Normal Idle Speed: The idle speed of a car will vary between cold and hot engine conditions. Generally, for an engine in good working condition when hot, the idle speed is usually between 550-800 RPM.

Why is the Lavida's fuel consumption so high?

Lavida's high fuel consumption is mainly due to tire pressure being below standard and inaccurate four-wheel alignment. Below are specific explanations for Lavida's high fuel consumption: 1. Tire issues: When tire pressure is below standard, it increases the tire's contact area and rolling resistance, leading to wear on both tire shoulders and higher fuel consumption. The recommended inflation pressure is 0.1471~0.490MPa (1.5~5kg/cm²), with low-pressure tires generally suitable for private vehicles. Typically, the inflation pressure for household cars is 0.2~0.25MPa. 2. Inaccurate four-wheel alignment: If the vehicle's four-wheel alignment is off (incorrect toe and camber angles), it increases friction between the tires and the ground, damaging the tires and also raising fuel consumption.

How to Choose Car Configurations When Buying a Car?

When buying a car, you can select configurations based on three aspects: safety, operational convenience, and others. First, consider safety-related configurations. Next are some high-tech features inside the car that make operations simpler, more convenient, and more user-friendly. Finally, there are some completely useless configurations. The details are as follows: 1. Safety configurations: Not all safety features are worth purchasing. For example, the number of airbags is very useful. Current car models generally come standard with four airbags—two in the front to protect the driver and front passenger, and two in the rear to protect backseat passengers. Volvo, known for its safety, offers some models with nearly thirty airbags and curtains. This level of protection is undoubtedly different from that of just four airbags. 2. Practical configurations: Features like tire pressure monitoring, ESP (Electronic Stability Program), ABS+EBD, rearview cameras, and dash cams can make driving simpler and more convenient. 3. Meaningless configurations: The automatic headlight cleaning function is the first to come to mind. It’s estimated that 90% of people have never used it. Other examples include hill descent control, brake assist, adaptive headlights, and built-in navigation—all of which are more flashy than practical. Ultimately, the choice of configurations should depend on the car owner’s personal preferences and usual driving environment. What one person finds useless, another might highly appreciate.
