Honda CRV idling shakes chicken feet after changing the reason for the shake

Main causes of idle jitter:

1. The most common cause of vehicle shaking is that the throttle is too dirty or the fuel injector has too much carbon.

2. When the carbon deposition inside the engine is too much, the gasoline sprayed by the cold start fuel injector will be absorbed by a large amount of carbon deposition, resulting in the mixture of cold start being too thin, making it difficult to start, in this case, only when the gasoline absorbed by carbon deposition is saturated, it is easy to get started, 3. After the car is adsorbed, the gasoline adsorbed on the carbon deposition will be sucked into the cylinder by the vacuum suction of the engine for combustion, and the mixture becomes thick, and the combustible mixture of the engine is dilute and thick, resulting in idle shaking after cold start. The lower the temperature, the greater the amount of oil required for the cold start, and the more carbon deposits will affect the smooth cold start.

Severe idle vibration is generally caused by engine cylinder failure, aging or loose foot rubber, carbon deposits, fuel system failure, etc.

Solution; The best way is to clean the oil circuit, clean it regularly, and use PNF fuel additives to solve the above problems caused by carbon deposits. The fuel quality is not very good or the initial fuel of the new car is stored for too long, resulting in a rapid increase in the colloidal composition of the oil circuit, which will continue to pollute the fresh fuel and cause no good fuel to participate in combustion in the later stage, and the carbon deposition exceeds the standard, which is especially common for China VI vehicles. We can only gradually alleviate most of the problems by maintaining clean oil circuits.

It could be the following problem:

The engine has serious carbon deposit, the throttle valve is too dirty, or the fuel injector has too much carbon deposit. When there is too much carbon deposit inside the engine, the gasoline sprayed by the cold start injector will be absorbed by the carbon deposit, resulting in the cold start mixture being too thin, making it difficult to start.

Ignition system problems, check the working condition of the spark plug, high-voltage wire and ignition coil, poor ignition system work, spark plug flashing condition is not good, will also lead to this kind of failure.

The oil pressure is unstable, if the oil pump supply pressure is not normal, or the intake pressure sensor has an incorrect value and poor work, it will cause the body to shake.

The engine foot is actually the suspension system of the engine, and the engine foot is responsible for absorbing the subtle shake of the engine when it is running, and if there is a problem with the engine foot, these vibrations will be transmitted to the steering wheel and cab, causing shaking when idling.

Hope it helps.

Check the engine floor pads for age.

The jitter is obvious when the combustion is not good at low idle speed, and when the speed increases, the fuel injection increases to cover up the problem of insufficient fuel injection for combustion. So the problem is in the fuel combustion of this relief, most of the problem is that the oil road is dirty, there is no direct relationship between the dirty road and the kilometer book, if the new car encounters oil impurities exceeding the standard to catch up with the direct injection car will also be common detonation shake. My experience is that using Specco's Fuel Cleaner twice can eliminate such jitter.

It's easy to use. If it is a car with more kilometers, it will produce carbon deposits, and the carbon deposits will be too thick and will detonate, and the carbon deposits can be cleaned, and the car will run fine, which means that the accessories are no problem and do not need to change the accessories. Using No. 95 fuel is to cover up the problem, and it will detonate after a long time, so don't cover up the problem when you solve the problem.

The causes of car idle jitter may be: faulty spark plug or ignition coil; Incorrect valve timing; uneven compression of the cylinder;

The valve seal is not tight, and there is air leakage; poor fuel pressure; Fuel injector plugging leakage; leakage between the cooling system and the cylinder; Air flow.

Sensor failure.

Classification of unstable idling.

1.How to observe unstable idling.

Observe the degree of shaking of the engine block, you can also ** the degree of shaking of the dipstick handle, and the smooth dipstick handle is very clear and shaking.

The dipstick handle looks double; Observed from the engine tachometer or reading data block, the rpm is jitter centered on the idle expected value, or.

Sharp shaking on the expected side, the expected idle speed in the program includes the standard idle value, load (light on, automatic transmission.

Hang the upper gear, etc.) idle value, air conditioning idle value, warm car idle value; Start the engine on the spot and feel the body violently while sitting in the seat.

Dithering. 2.Classified according to the law of appearance.

Cold car (coolant temperature below 50) rhythmic instability; Hot cars (coolant temperatures above 50) are rhythmically unstable.

Irregular, violent shaking.

One, two. 3. Classification according to the degree of jitter.

Normal, with the expected value of 10r min shaking at idle speed; Generally unstable, with an expected idle speed of 20r min jitter; Seriously not.

Stable, exceeding the expected idle speed by 20r min jitter; Shake violently on the side of the idle expectation.

4.Categorized by reason association.

The direct cause refers to the dirty, worn, incorrect installation of mechanical parts, etc., which leads to the change of individual cylinder power, resulting in each.

The power of the cylinder is unbalanced, resulting in unstable idle speed of the engine; Indirect causes refer to the abnormal electronic control system of the engine, resulting in mixing.

Poor combustion of the combined gas makes it difficult to balance the power of each cylinder, resulting in unstable engine idling.

5.Classified by faulty system.

air intake system; ignition system; Motor.

Summary. Pros ( Hello, the car parking has a feeling of shaking, it is recommended to do the following checks:

First, this is more common is the vehicle spark plug aging or ignition coil damage caused by this situation, this can go to the repair shop to disassemble the spark plug, check the amount of spark plug clearance, if the gap is too large, or the wear is more serious, generally replace the spark plug can solve the problem. The inspection of the ignition coil needs to use the computer to read the specific fault code, if the corresponding cylinder has a misfire, it is generally a problem with the ignition coil.

Second, the engine has too much carbon deposit, which causes idle jitter.

In this case, it is recommended to clean the carbon deposits in the engine, especially the carbon deposits in the intake tract and cylinder of the throttle. The carbon deposits in the cylinder are mainly the carbon deposits at the piston position and the valve base position, and then rematch the throttle!

Third, the fault caused by the failure of the oil circuit, this needs to test whether the fuel supply pressure of the gasoline pump is normal, if the oil supply pressure is unstable, you need to replace the new gasoline filter element in time, and clean the fuel injector.

Original. What is the cause of Dongfeng Honda CRV engine idle jitter?

Cai Jinsheng. Car maintenance tips·2022-10-26

1. If you have cleaned the carbon deposits in the engine, washed the throttle carefully, changed the oil cushion and spark plug, etc., and still found that the body shakes when idling, you can go to the 4S shop to check the fuel supply pressure and intake pressure sensing of the base oil.

If the oil pump supply pressure is abnormal or the intake pressure sensor is wrong and working poorly, it will cause the body to shake. Resolved.

The method is to check the oil pressure and replace the parts if necessary;

2. The silver foot is actually the shock absorption system of the engine, and the engine foot is responsible for absorbing the subtle shaking of the engine when it is running.

If something goes wrong, these vibrations are transmitted to the steering wheel and cab.

Inside; 3. When there is too much carbon deposit, the gasoline sprayed by the cold-start fuel injector will be.

A large amount of carbon deposition is absorbed, resulting in the cold start of the mixture is too thin, and the start is filial piety.

It is difficult, and the gasoline that adheres to the carbon deposits after hitting the car will be started again.

The vacuum suction of the machine is sucked into the cylinder for combustion, so that the mixture becomes thick, and the combustible mixture of the engine is dilute and thick, resulting in idle shaking.

The solution is to clean the oil circuit and check whether there is any accumulation in the idle motor.

The carbon should be cleaned.

The main reasons for the low idle jitter of the Honda CRV may be: spark plug or ignition coil failure; Incorrect valve timing; uneven compression of the cylinder; The valve seal is not tightly searched, and the air leaks; fuel pressure differential; nozzle clogging and leakage; leakage between the cooling system and the cylinder; The air flow sensor is faulty.

Causes and solutions to Honda CRV low idle jitter:

1.The engine has a lot of carbon deposits. When there is too much carbon inside the engine, the gasoline sprayed by the cold start injector will be absorbed by a large amount of carbon deposit, making the cold start mixture too thin and difficult to start.

In this case, it is easy to drive until the absorbed gasoline is saturated with carbon deposits. After driving, the gasoline adsorbed on the carbon deposits will be sucked into the cylinder by the vacuum suction of the engine for combustion, making the mixture thick and the engine combustible.

2.There is a problem with the ignition system. Check the operation of spark plugs, high-voltage wires, and ignition coils. Poor ignition system work and poor ignition conditions of the spark plug can also cause such failures. The solution is to check the spark plug and replace it.

3.The oil pressure is unstable. If the engine has been cleaned of carbon accumulation, the throttle valve has been cleaned, the oil pad and spark plug have been replaced, etc.

You'll still find your body rocking at idle. It is recommended that you go to the 4S shop to check whether the oil supply pressure and inlet pressure sensors are normal. If the oil pump supply pressure is abnormal, or the intake pressure sensor has the wrong value, it will work poorly, which will cause the body to shake.

The solution is to check the oil pressure and replace the parts if necessary.

There are many reasons for car jitter, it can be too much carbon accumulation on the throttle, aging engine floor pads, or it can be a lack of cylinders in the engine. The lack of cylinder is caused by a faulty ignition system. The main components of the ignition system include the ignition coil and the spark plug.

Causes of idle jitter:

1. The engine has serious carbon deposits. The most common cause of idle judder is excessive carbon build-up on the throttle or injector. When there is too much carbon deposition inside the engine, the gasoline sprayed by the fuel injector during cold start will be absorbed by a large amount of carbon deposition, resulting in too thin mixture, making it difficult to start.

After the car is hit, the gasoline adsorbed on the carbon deposits will be sucked into the cylinder by the engine for combustion, which will make the mixture thicker. The mixture is sometimes dilute and sometimes thick, which will cause idle jitter after cold start. The lower the temperature, the greater the amount of oil required for cold starts, and the more the presence of carbon deposits affects cold starts.

The solution to the problem is to clean the carbon deposits at the throttle and fuel injector.

2. Poor ignition system and poor ignition of spark plugs will also lead to engine idling and shaking. If there is a problem, check if the ignition system is faulty and if there is too much carbon deposited in the spark plug.

3. The oil pressure is unstable. If you have cleaned the engine carbon deposits, cleaned the throttle valve or replaced the spark plug, and there is still the problem of body shaking when idling, it is recommended to go to the 4S shop to check whether the fuel supply pressure and intake pressure sensor are normal. If the oil pump supply pressure is not normal or the intake pressure sensor is incorrect, it can also cause the body to shake when idling.

Solution; The best way is to clean the oil circuit, clean it regularly, there is no specific experience in the research and development parameters of the clean engine from the new car, coupled with the continuous improvement of emission standards, can not adapt to the change of fuel, all manufacturers of the engine are unable to solve this jitter problem in the short term, plus the fuel quality is not very good or the initial fuel of the new car factory is stored for too long, resulting in a rapid increase in the colloidal composition of the oil circuit, which will continue to pollute the fresh fuel and cause no good fuel to participate in combustion in the later stage. The occurrence of excessive carbon deposits is especially common for China VI vehicles. We can only gradually alleviate most of the problems by maintaining clean oil circuits. The use of PNF dope fuel additives can solve the problems caused by carbon deposition.
