What is the reason why cars are boring?

The reasons why cars are boring are as follows: 1. The oil circuit system is the place where the car often has problems. Blocked nozzle, oil leakage from oil pipe, reduced power of gasoline pump and blocked gasoline filter will all lead to the car going uphill. The reason why the car feels weak is mainly because the engine oil is not enough when going uphill, the combustion efficiency decreases and the horsepower can not meet the requirements. 2. The engine needs air besides oil. If the air filter, throttle and other parts are blocked or have problems and the air intake is insufficient, it will also cause the car to accelerate slowly. 3. Spark plugs are also the source of common faults. If the spark plug is not ignited properly, it may lead to the problem of weak acceleration. 4. If the car is boring, you will feel that the steering wheel or body will shake obviously when the car stops, indicating that at least one cylinder of the car's engine is not working properly or is turned off. If you turn on the air conditioner in summer, it will be very difficult for such a small-displacement car to accelerate, and the fuel consumption will increase obviously. 6. Insufficient tire pressure will also lead to the acceleration of the car.
