Does the x1000rpm need to be eliminated?

There is no need to eliminate the x1000rpm, as it indicates thousands of revolutions per minute of the engine and is not a fault code. An engine speed between 1000 and 3500 rpm is optimal for the engine. The reasons for high engine speed include: 1. Sudden increase in throttle opening; 2. Fuel injector leakage or clogging; 3. Slippage or damage to the air conditioning clutch; 4. Air intake system leakage; 5. Insufficient engine power output. Solutions for high engine speed include: 1. Adjusting the throttle opening; 2. Replacing the fuel injector, air conditioning clutch, air intake system, or engine. Engine maintenance methods include: 1. Using qualified engine oil; 2. Using qualified coolant and antifreeze; 3. Regularly cleaning the radiator scale; 4. Regularly removing engine carbon deposits; 5. Regularly replacing the three filters of the car; 6. Maintaining a reasonable engine speed.

I've been driving for several years, and every time I look at the dashboard, I notice that x1000rpm mark. At first, I wondered if I needed to do anything about it. Later, I specifically asked a mechanic, who said it doesn't need to be removed at all. This is actually the unit identifier for the tachometer, telling you that 1 on the dial corresponds to 1000 revolutions in reality. For example, if the needle points to 2, it means 2000 rpm, and if it points to 0.8, it means 800 rpm. All gasoline car tachometers are marked this way. If you actually erase it, it might affect your judgment of the engine's condition. It's recommended to pay more attention to the actual rpm range in daily use. A cold start idle speed of 1200 rpm is normal, and maintaining around 800 rpm after the engine warms up is ideal. As long as the car doesn't have abnormal vibrations or strange noises, you can completely ignore this mark.
