Here are the steps to address power loss in a car after turning on the air conditioning: 1. Inspect the vehicle to check for any faults. A common issue is air conditioning malfunction, especially during summer when the AC is used daily. It could be a problem with the thermostat or clutch. The main approach is to turn off the AC and observe the car's performance. If the car performs better without the AC, it indicates an AC issue, and you should visit a professional repair shop for inspection. If the car still struggles, the problem likely lies elsewhere. 2. Replace the spark plugs. Changing spark plugs is a key method to enhance vehicle power. Spark plugs play a significant role, and different materials yield varying results. High-quality spark plugs not only extend their lifespan but also improve power output. Another method is to increase the voltage of the high-voltage coil or replace standard high-voltage ignition wires with high-energy ones. 3. Check the engine oil. The lubricating effect of engine oil is crucial for the car. A car cannot function without engine oil, much like how blood is essential for humans. Good-quality engine oil reduces wear between car components, so regularly check the oil level. Insufficient oil can lead to increased wear on car parts. 4. Remove carbon deposits from the engine. Carbon buildup is a common issue, especially when drivers have poor driving habits or use low-quality gasoline. Regular inspection and cleaning, along with preventive measures in driving behavior, are the best maintenance practices for the car. This also ensures the engine provides optimal power.

What Causes the Odyssey to Shake?

Odyssey shaking reasons are as follows: Severe Carbon Buildup: The most common cause of shaking is a dirty throttle body or excessive carbon buildup in the fuel injectors. When there is too much carbon buildup inside the engine, the gasoline sprayed by the cold-start injector is largely absorbed by the carbon deposits, resulting in an overly lean air-fuel mixture during cold starts. This makes starting difficult. Under these conditions, the engine will only start easily once the carbon deposits have absorbed enough gasoline to reach saturation. After starting, the gasoline adsorbed on the carbon deposits is then sucked into the combustion chamber by the engine's vacuum, making the air-fuel mixture overly rich. The engine's combustible mixture alternates between lean and rich, causing idle shaking after a cold start. The lower the temperature, the more fuel is required for a cold start, and the presence of carbon deposits will significantly affect whether the cold start proceeds smoothly. The solution is to clean the fuel system and check the idle control valve for carbon buildup, which should be cleaned if necessary. Ignition System Issues: Check the condition of the spark plugs, high-voltage wires, and ignition coils. Poor performance in the ignition system or weak sparking from the spark plugs can also lead to such symptoms. The solution is to check if the spark plugs have excessive carbon buildup and replace them if necessary. Unstable Fuel Pressure: If you have already cleaned the engine carbon deposits, throttle body, replaced gaskets, and spark plugs but still notice shaking at idle, it is recommended to visit a 4S shop to check the fuel supply pressure and the intake pressure sensor. Abnormal fuel pump pressure or incorrect readings and poor performance from the intake pressure sensor can cause the vehicle to shake. The solution is to check the fuel pressure and replace components if necessary. Aging Engine Components: Vehicle shaking can also be related to worn engine mounts. Engine mounts act as the engine's shock absorption system, absorbing minor vibrations during operation. If the engine mounts are faulty, these vibrations will transfer to the steering wheel and the cabin, causing shaking at idle.

What Causes the Needles on the Tiguan Dashboard to Jump Randomly?

After prolonged discharge, the battery voltage may drop too low, possibly due to loose or corroded grounding points, or certain electrical components that have accumulated severe carbon buildup or even poor connections after extended use. The dashboard operates within a specific voltage range, typically around 9~16V. When the dashboard completely loses power or operates at an excessively low voltage and then regains power, all needles on the dashboard will perform a reset operation. During this process, you may hear "squeaking" or "clicking" sounds, which are normal for the dashboard. You can test this with a new car by disconnecting and reconnecting the negative terminal of the battery—this sound will definitely occur. Higher-quality motors produce quieter sounds.
