Why does the engine shake at idle but stops shaking when accelerating?

Here are the reasons why a car may experience shaking: 1. Excessive carbon deposits. Severe carbon buildup in the engine cylinders can lead to clogged spark plugs and valves, directly causing the car to shake at idle. If the vehicle's acceleration performance has significantly declined and the shaking is persistent, consider an engine cylinder cleaning. 2. Fuel supply system malfunction. Unstable fuel pressure can easily cause fluctuations in the air-fuel mixture concentration, not only resulting in shaking but also causing unstable idle conditions. 3. Worn engine mounts. This is also a very common cause of shaking. If your car's engine shake is becoming increasingly severe but the power output hasn't weakened accordingly, it may be time to check the engine mounts. 4. Misfiring cylinders. This is the most frequent cause of engine shaking. The issue typically lies with the engine's ignition coils or spark plugs. If there's a problem with the ignition coil or if the spark plug fails to fire for some reason, the car will exhibit shaking symptoms.

How to Fix a Broken Tachometer in Mitsubishi Pajero?

If the tachometer in a Mitsubishi Pajero is broken, it cannot be repaired and must be replaced. The advantages of the car tachometer's operation are as follows: 1. High static torque, the pointer is not prone to shaking, and it has strong anti-vibration performance; 2. It uses a single-chip microprocessor through software design, so it has high precision and strong anti-interference capability; 3. The hour meter uses LCD display, without mechanical parts, making it more reliable and modern. Extended content: The working principle of the car tachometer is that the tachometer receives digital pulse signals (sent by the sensor), processes them, and directly reads them into the CPU's counting port. The software calculates the speed and the corresponding position of the pointer, then through the CPU's control port, amplifies and drives the stepper motor to rotate in both positive and negative directions, indicating the corresponding speed value (the pointer is directly installed on the rotating shaft of the stepper motor). Each step of the stepper motor is only 1/3 degree.

Should the Warm Air Blow at the Feet or the Windshield in Winter?

When using the warm air in winter, you can adjust the direction and position of the air vents according to your needs. If there is fog on the car's windshield, you can direct the air vent towards the windshield. Here are some specific details: 1. Every car owner knows how to operate the warm air function of the air conditioning, but there are some precautions to keep in mind during use. When the car is in a cold start state, the engine's water temperature does not rise quickly. At this time, you should not turn on the warm air because the engine's water temperature is too low. Immediately using the warm air will not only fail to raise the temperature inside the car but also hinder the normal rise of the engine's temperature. 2. The correct way to use it is to start the engine and let it warm up for about 5-10 minutes. Only after the engine's water temperature rises should you then use the warm air.
