Throttle cleaning crv

1. Serious engine carbon deposit: There have been carbon deposit problems in automobiles, including cylinder carbon deposit, throttle carbon deposit, spark plug carbon deposit, intake carbon deposit and so on. When the engine has too much carbon deposit, it will affect the ignition energy, intake efficiency and air-fuel ratio of the automobile, resulting in unstable power output, idle speed and acceleration jitter.

2. Unstable oil pressure: If you have cleaned the engine carbon deposit, cleaned the throttle, replaced the oil pad and spark plug, etc. And the body is still shaking when idling. I suggest you go to the 4S shop to check whether the oil supply pressure and intake pressure sensors are normal. If the oil supply pressure of the oil pump is abnormal, or the intake pressure sensor is wrong and works badly, it will lead to the body shaking.

3. Engine cylinder shortage: Engine cylinder shortage mainly refers to the abnormal operation of one or more cylinders of the engine, which is generally manifested as: the exhaust gas flowing out of the car is obviously intermittent, the exhaust pipe is violently shaken, and the engine jitter can be obviously felt, sometimes accompanied by abnormal noise. This is mostly related to ignition coil failure.

4. Aging of engine parts: Car jitter is also related to the aging of engine feet (also known as claw pads). The engine foot is actually the damping system of the engine. The engine feet are responsible for absorbing slight vibration when the engine is running. If there is something wrong with the engine base, these vibrations will be transmitted to the steering wheel and cab, causing idle vibration.

Solutions;

The best way is to clean the oil circuit, clean it regularly and use fuel additives such as PNF stock solution to solve the above problems caused by carbon deposition. The poor quality of fuel or the long storage time of fuel in the initial stage of a new car will lead to the rapid increase of colloidal components in the oil circuit, which will continuously pollute the fresh fuel, resulting in no good fuel to participate in the combustion in the later stage, and the carbon deposition exceeds the standard, especially for the national six cars. Only by maintaining a clean oil circuit can most problems be gradually alleviated.
