Zhijun is not good at starting, the idle speed is unstable, and the engine is shaking

Hello, this situation may be caused by excessive carbon deposition or lack of cylinder in the engine, it is recommended to clean the throttle first and replace the spark plug.

According to the phenomenon said by the landlord, I personally feel that it is basically caused by serious carbon deposits in the engine, and I will first clean the lower throttle, and I will not be able to clean the air intake under the hanging bottle, etc., and there will be improvement.

This may be caused by serious carbon deposits in the engine, and it is recommended to clean the throttle and fuel injector.

In this case, check whether the vehicle is caused by the lack of cylinders, and whether the working condition of the spark plug is too much carbon deposit. Check it out.

Hello, the vehicle is not good to start to check whether the battery voltage is normal, and there is a more serious carbon deposition plot to try carbon deposition.

In this case, first check whether it is caused by carbon deposits. Look at the throttle, fuel injector and spark plug to see if there is serious carbon deposit?

In this case, it is generally possible that it is caused by excessive carbon deposits in the engine, and it is recommended to check and clean up the carbon deposits in the engine.

Hello, if there is such a phenomenon, first check whether it is caused by too much carbon deposit. Also check the ignition coil and the high-voltage wire for problems.

Hello, your situation may be caused by too much carbon deposition in the engine of the car, it is recommended to go to the 4S shop to clean it.

Hello, this problem should be caused by serious carbon deposits in the engine, you can go to the 4S shop to clean and replace the spark plugs.

Hello, is it an electronic throttle or a mechanical one? Are there any fault codes?

Santana Zhijun idle shake steering wheel also shakes Idle shake can check the pointer of the idle speed meter is not firm, the general performance is poor incineration, if it is a new car The bottom will not have the problem of idle component hazards, because the incineration requirements of the turbo direct injection vehicle are very engaged, or clean the oil circuit first, before the idle pointer is not firm, the idle speed flutter in the fuel tank to participate in the division of general fuel additives after running two tanks of oil is completely good.

The steering wheel shakes when the car is idling, which is very common, and some car owners can feel a strong steering wheel shake when driving the car at high speeds, when the speed reaches 80-100km h or more. In this case, most of the problems occur in the tires of the car, because the uneven distribution of the mass of the whole part of the tire will cause the wheels to rotate at high speed, and there will be a dynamic imbalance state, which will cause the steering wheel of the car to shake seriously while driving. In this case, it is necessary to align and dynamically balance the tires of the car, and in serious cases, the tires must be replaced.

In addition to the tires of the car, there may also be shock absorber failure, frame deformation, excessive meshing clearance of the main and driven gears of the final reducer, etc. If the steering wheel shakes when braking while driving, then it is very likely that the brake force is too strong and too frequent, which may cause the brake disc and brake pads to overheat and deform when cold, causing the steering wheel to shake.

Generally, the symptoms can be solved after replacing the brake discs and brake pads. If the speed of the vehicle is not fast, but the steering wheel shakes, it is possible that the steering belt of the mechanical steering system will slip when the belt is too loose, which will also cause the steering wheel to shake, and there will be shaking and abnormal noise when the steering transmission system is loose and the gap is too large, but this situation is rare.

Air filter dirty:

The air filter is designed to protect the engine to reduce wear, generally replaced in about 10,000 kilometers, if the replacement is not timely, there will be insufficient air intake to cause low idle speed, and the engine shakes, as long as the filter element can be replaced.

High-voltage line break: High-voltage line break refers to the high-voltage wire core break, which can affect the ignition and cause the engine to shake.

Spark plug life:

The spark plug has a lifespan, and the ignition efficiency is significantly reduced after more than 3-40,000 kilometers, and can affect the ignition, which is the most common failure.

Low idle speed: The engine idle speed value has been set in the computer, and when the number of revolutions is low to a certain range, the car computer will automatically adjust it. If the idle speed is too low and the jitter is beyond the control range of the computer, some cars have adjusting screws on the throttle to adjust the idle speed, and some cars can not adjust, this kind of car can check the idle valve, throttle, air flow meter, vacuum sensor, adjust the ignition time (car with distributor), you can increase the idle speed.

Low idle speed can occur even when the water temperature is low, so you can check and replace the thermostat.

The water temperature is not normal:

There is a normal range of engine operating temperatures, and high water temperatures will cause earlier ignition times, changes in the oil-air mixing ratio, thinner oil viscosity, and worse lubrication performance. The general fault cause is the jitter caused by the lack of antifreeze, the thermostat cannot be opened, the fan does not rotate, and the temperature of the temperature control switch is inaccurate.

Fuel injector clogged:

The fuel injector of the EFI vehicle is a key component of automobile fuel injection, and the service life is very long, which can reach hundreds of thousands of kilometers. However, because there is gum in the gasoline, the fuel injection hole of the fuel injector will be blocked, so the amount of fuel injected by each fuel injector is inconsistent, resulting in the inconsistent work of each cylinder and causing the engine to shake. The solution is to remove it and clean it.

Carbon deposits, grease blockages:

The throttle, idle valve, and air intake hole will be blocked by carbon deposits, oil scale, and poor air intake after a period of use, which will affect the stable idle speed and shaking. It is necessary to inspect and clean the above parts with cleaning agent, and there is no need to remove them for cleaning.

Low cylinder pressure: The engine has 3 cylinders, 4 cylinders, 5 cylinders, 6 cylinders, and 8 cylinders. Three-cylinder engines are the most obvious, followed by four-cylinders. Check the cylinder pressure with the cylinder pressure gauge, and solve the fault of low pressure with Xinba.

Xinba has a unique effect on low cylinder pressure and unbalance. It can be added to the engine oil or directly added to the cylinder to restore the balance cylinder pressure.

The common problems of Zhijun cars are: sudden engine stalling while driving, sudden steering failure, car tire puncture andSpontaneous combustion of the car**；Vibration and noise of automobiles have increased significantly; Fuel leaks, oil leaks,CoolantLeakageBrake fluidLeakage, leakage of battery fluid in the electrical system and leakage of the source difference system of the electrical system.

The causes and solutions of Zhijun's idle vibration are: 1. The engine has serious carbon deposits, and the reason why the car shakes and vibrates is very common is that the throttle is too dirty and the nozzle has too much carbon deposit. Workaround:

Clean the oil circuit and check whether the idle motor has carbon deposits; 2. Check the ignition system problems, the working conditions of the spark plugs, high-voltage wires and ignition coils, and the poor working of the ignition system and the poor flashing of the spark plugs will also affect such fault phenomena. Solution: Check whether the spark plug has too much carbon deposit, and replace the spark plug; 3. Hydraulic instability, even if the engine is depositioned, hail throttle cleaning, oil cushion replacement, spark plug replacement, etc., if the body shakes and vibrates when idling, it is recommended to detect whether the fuel supply pressure and intake pressure sensor are normal in the 4S store, and the oil pump supply pressure is abnormal, or the intake pressure sensor is wrong or not working properly, which will basically cause the body to shake and vibrate.

Solution: Detect the hydraulic pressure and replace the parts if necessary; 4. The aging of engine parts and the shaking and vibration of the car are also related to the aging of the engine feet (also known as mechanical claw pads). I think that the foot of the engine is the vibration isolation system of the engine sedan.

The feet of the engine absorb the vibrations that tremble slightly as the engine rotates. If there is a problem with the engine's feet, these vibrations can be transmitted to the steering wheel and travel compartment, causing trembling vibrations at idle. Workaround:

Replacement parts.

The cause of Zhijun's idle jitter may be carbon deposits on the throttle and injector, which can be solved by cleaning the throttle, injector, and idle motor. If the car shakes while driving and the accelerator pedal shakes the foot, it means that the engine's chicken paw pad is faulty and needs to be replaced.

The other situation is more serious, which may be caused by the deformation of the steel rim, and the owner needs to go to a professional repair shop for inspection. This usually happens with vehicles that have a long lifespan. Generally, when replacing new tires and new rims, it is necessary to do a good job of wheel balance, otherwise the steering wheel is easy to shake when the weight is uneven.

The body shakes will affect the driving comfort and handling judgment. It may also be caused by the deformation of the transmission shaft and the imbalance of the first group. Generally, this happens when the chassis collides with more cars.

Idle shake can mean one of three things in your vehicle:

1.The engine has a lot of carbon deposits.

The most common cause of car shake is that the throttle is too dirty or the injector has too much carbon. When there is too much carbon deposition inside the engine, the gasoline emitted by the cold start injector will be absorbed by a large amount of carbon deposit, resulting in too thin cold start mixture and difficult starting. In this case, it is easy to start the car only when the gasoline adsorbed with carbon deposits is saturated, and the gasoline adsorbed on the carbon deposits after starting the car will be sucked into the cylinder by the vacuum suction of the engine for combustion, so that the mixture becomes thicker, and the combustible mixture of the engine becomes thinner and thicker, resulting in a cold start.

The lower the temperature, the greater the amount of oil required for the cold start, and the more carbon will be deposited, which will affect the success of the cold start. The solution is to clean the oil circuit and check whether the idle motor has carbon deposits, which should be cleaned.

2.Problems with the ignition system.

Check the operation of the spark plugs, high-voltage wires, and ignition coils. If the ignition system is not good to use, the spark plug does not jump, which will also lead to such a failure. The solution is to check the spark plug for excessive carbon deposits and replace the spark plug.

3.The oil pressure is unstable.

If the engine carbon deposits have been cleaned, the throttle valve has been cleaned, the oil pads and spark plugs have been replaced, etc. If the oil pump supply pressure is abnormal, or the value of the intake pressure sensor is wrong and working poorly, it will cause the body to shake. The solution is to check the oil pressure and replace the parts if necessary.

4.Aging of engine components.

Car shake is also associated with aging of the engine feet, also known as claw pads. The engine foot is actually the shock absorber system of the engine. The engine feet are responsible for absorbing slight vibrations when the engine is running.

If there is a problem with the base of the Hair Orange motor, these vibrations can be transmitted to the steering wheel and cab, causing vibrations at idle. The solution is to replace the parts.

Millions of car purchase subsidies.

Zhijun The cause of idle jitter may be caused by carbon accumulation on the throttle and fuel injector, which can be solved by cleaning the throttle, fuel injector and idle motor. If the car also shakes while driving, and the accelerator pedal shakes the foot, it means that the engine chicken paw pad is faulty and needs to be replaced.

The other condition is more serious, which may be caused by the deformation of the steel rim, which requires the owner to go to a professional repair shop for inspection. This condition usually occurs in vehicles that are more than a year old. Generally, when the car is replaced with new tires and new steel rims, it is necessary to do a tire balance, otherwise the steering wheel will be prone to shake when the counterweight is uneven.

Body shake will have an impact on driving comfort and handling judgment. It may also be caused by the unbalanced deformation of the drive shaft, which generally occurs in more cars that have collided with the chassis.

Idle body shake can indicate one of three conditions in the vehicle:

1.The engine has a lot of carbon deposits.

The most common cause of car shake is a dirty throttle or excessive carbon build-up in the fuel injector. When the carbon deposition inside the engine is excessive, the gasoline sprayed by the cold start fuel injector will be absorbed by the carbon deposition in large quantities, 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 on the car, and the gasoline adsorbed on the carbon deposition after the car 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, causing 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.

The solution is to clean the oil circuit and check whether the idle motor has carbon deposits that should be cleaned.

2.Problems with the ignition system.

Check the working condition of the spark plug, high-voltage wire and ignition coil, the ignition system is not working well, and the spark plug tripping condition is not good, which will also lead to this kind of failure. The solution is to check the spark plug for excessive carbon build-up and replace the spark plug.

3.The oil pressure is unstable.

If you have cleaned the engine carbon deposit, washed the throttle, changed the oil pad and spark plug, etc., and still found that the body shakes when idling, it is recommended that you 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 abnormal or the intake pressure sensor value is wrong and the work is not good, the body shake will be triggered. The solution is to check the oil pressure and replace the parts if necessary.

4. Aging of engine parts.

Car jitter is also related to the aging of the engine feet (also known as claw pads). 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. The solution is to replace the parts.
