1 Answers
When driving at 120 km/h on the highway, the normal RPM range is between 2000 and 3500. The reasons for high RPM include: 1. Sudden increase in throttle opening; 2. Fuel injector leakage or blockage; 3. Slipping or damage to the air conditioning clutch; 4. Air intake system leakage; 5. Insufficient engine power output. Solutions for high RPM are: 1. Adjust the throttle opening; 2. Replace the fuel injector, air conditioning clutch, air intake system, or engine. Driving precautions include: 1. Avoid emergency braking and rapid acceleration during the break-in period; 2. Do not overload the vehicle within the first 1000 kilometers; 3. Observe speed limits during the new car break-in period, ensuring moderate speed driving; 4. Avoid prolonged driving to allow the car time to adjust; 5. Change the engine oil according to the manufacturer's specified intervals during the break-in period; 6. Avoid driving at a constant speed for extended periods.
