What happens when the idle speed is 600 rpm shake and 800 rpm is not shaken?

It is recommended that you clean the throttle valve, check the quality of gasoline in another aspect, and also need to check the exhaust valve, and there may be a blockage of the fuel injector, and then check whether the ignition is good, especially the ignition coil and spark plug.

Hello, the normal idle speed should be 800 to 900, 600 is too low, it may shake, or it may be because the engine has too much carbon deposit, clean the throttle and fuel injector to try.

The idle speed of 600 rpm shakes is because the idle speed is too low, and seven or eight hundred rpm is normal, so it will not shake.

Hello, if the idle speed of the engine is about 600 rpm, it means that the idle speed is low, and it is best to clean the throttle.

Hello, according to what you said in this situation, it should be that the idle speed is a little low, and it is recommended to clean the throttle.

You seem to have this situation mainly due to the low engine speed, this first needs to rule out whether the engine is missing cylinders, if the engine is not lacking cylinders, then you need to check whether the idle valve is normal.

This is obviously the reason for the low idle speed, check the idle motor, you can adjust it appropriately, and check whether there is too much carbon deposit.

The main reason is that the idle speed is too low. Adjust the idle motor to check if it is caused by too much carbon deposit.

That's because idling 600 is too low, idling 800 is normal, and if it's too low, it won't work.

This is that the idle speed is too low, and this 600 rpm should be considered to detect whether it is caused by serious carbon deposition on the throttle.

Hello, if the idle speed is too low, it is easy to cause shaking, you can go and clean the throttle and fuel injector deposit

The idle speed of 600 rpm is a bit low. 800 rpm idle speed is normal, you can adjust the idle speed.

Hello, generally speaking, the engine speed idle speed is about 750 rpm, if it is low, the engine runs smoothly and poorly, and it must shake back, especially for engines with 4 cylinders and below.

This idle speed of 600 rpm is a little low, 800 rpm is normal, you can refer to it.

Under normal circumstances, the idle speed of the engine is relatively normal at 750 rpm, which is relatively low, resulting in shaking.

Hello, it is recommended to check the spark plugs, and clean your throttle and fuel injector with the ignition coil.

Normal, engine speed 700 to 800 that there is no problem. If the 600 does not shake the vehicle travel is not bad,

The body shakes, and the engine is well lubricated after the car is warmed up, resulting in high idle speed! The engine is not fully lubricated at the start of the car.

Hello, it is recommended to go to the local 4S store to test the spark plug ignition coil and clean the throttle injector!

As long as it doesn't shake, there's no problem. Sometimes the tachometer of a vehicle is not 100% accurate.

Hello, the engine idle speed is a little lower at 600, and it is generally normal at 7 8 hundred.

Hello, according to your situation, this speed is still a bit low, it is recommended that you go to the local 4S shop or repair shop to check.

The idle speed of 600 rpm is jitter because the speed is a bit low, and 800 rpm is normal, you can refer to it.

Hello, this situation may be the reason why the throttle is too large, you can go to the 4S shop to clean the throttle, clean the fuel injector, and check the ignition performance of the spark plug.

CarsIdlingIt is normal to be below 800 revolutions per minute, and when the idle speed of the car cannot be lowered at 1000 rpm, this is caused by the phenomenon of stagnation of the idle control valve of the car, and the idle control valve of the car needs to be cleaned.

When the engine is running, if the accelerator pedal and the speed adjustment are completely relaxed, the engine is idling. The rotational speed at which the engine is idling is known as the idle speed. When the engine is running, if the accelerator pedal is completely relaxed, the engine is idling.

When adjusting the idle speed, the speed should not be high or low, otherwise it will cause early wear on the engine.

The difference between the idle speed of a car in a cold and hot state.

Engines that work well in hot car conditions mostly have an idle speed of 550-800 rpm. In the cold car state, the engine must be allowed to enter the normal working environment as soon as possible after the car starts, so when the cold car starts, the engine computer will automatically inject more fuel to quickly increase the water temperature of the engine by burning more fuel than the normal idle speed, so that the engine can quickly enter the appropriate temperature.

The main symptom is that the engine idle speed will be relatively high when the car is cold, most of them are at 950-1300 rpm, and when the engine temperature rises to a certain value, the idle speed will be reduced to a normal value.

Summary. Hello dear, the idle speed has been displayed at 1000 rpm, this is not normal, it is generally a problem with the throttle of the vehicle. First, in this case, it is recommended to clean the throttle and then redo the throttle matching.

For older models, if it still doesn't work, you need to replace the idle motor. Second, if the problem cannot be solved, check whether there is any air leakage in the vacuum pipeline of the air intake system? This focuses on checking the check valve for the vacuum line and the solenoid valve for the canister.

Thirdly, a problem with the vehicle's exhaust valve will also lead to an increase in idle speed, which requires a new exhaust valve. Dear, I wish you a happy family, if you have any other questions, you can continue to ask questions, I will always wait for your reply.

There are many reasons for this phenomenon, such as serious carbon deposition inside the engine, ignition system problems, unstable fuel pressure, aging of internal parts of the engine, etc

1. The internal carbon deposition of the engine is serious, which is often manifested in the carbon deposition of the throttle, the carbon deposition of the fuel injector, the carbon deposition of the spark plug, and the carbon deposition of the piston, which will absorb the combustion heat to a certain extent, and even the situation of deflagration and detonation.

2. The ignition system problem is generally due to excessive carbon deposition in the spark plug and insufficient ignition voltage, resulting in flashover, and even a single or multi-cylinder lack of fire, the engine will shake due to insufficient power, and when the shaking is serious, it will be between flameout and ignition;

3. The fuel pressure is unstable, the fuel system includes auxiliary devices such as gasoline tank, gasoline filter, gasoline pump, oil-gas separator, oil pipe and fuel gauge, if one of them has a problem, blockage or leakage, it will lead to unstable oil pressure, and the engine power will shake intermittently.

4. The internal parts of the engine are aging, usually this situation will only appear after a certain number of years or mileage of the vehicle, and the engine power will shake when the engine power drops seriously.

2. Air leakage from the vacuum tube.

3. Throttle position sensor failure.

4. Idle stepping motor failure.

5. The idle control valve fails.

6. The throttle opening is abnormal.

7. Air leakage in the air intake system.

Question: I just changed the battery for two days, and it's like this, what do I need to do.

I feel like it's an issue with the idle control valve.

Unplug the current sensor plug on the negative pole of the battery, plug it in and try again, perfect solution!

1.Oil Generally speaking, oil consumption is not severe enough to get through the cycle between maintenances, but in the summer due to the hot weather, oil consumption will be a little higher than usual. If it is found that there are impurities or gasoline smell in the engine oil during the daily inspection, and the exhaust smoke is light blue, it means that there is a problem with the engine, and the parts may be abnormally worn, so you should enter the factory for maintenance as soon as possible.

2.Transmission fluid.

When you change your engine oil, you can check your transmission oil by the way, and since the inspection process is more cumbersome, you can ask the dealer's service department to handle it. In order to measure accurately, the car must be discharged into neutral p, run at idle speed, and parked on a flat place, and the oil must run to an operating temperature of 80 93.

3.Too much or too little oil can damage the gearbox, and too much oil may cause excessive resistance to the operation of the parts, or cause the transmission oil to bubble and deteriorate, resulting in abnormal wear and tear of the parts. So when you check your transmission fluid, it's important to measure accurately.

4.Power steering oil.

When the engine cools down, wipe the top of the oil filler cap and the oil reservoir clean, then unscrew out the direction oil cap, and wipe the dipstick clean with a fiber-free clean paper towel, and then install the lock, and then open and pull out the oil level to check the dipstick.

To fill or change the oil, it is necessary to use the correct power steering oil, if it is not used properly, it will cause damage to the steering machine.

5.Brake fluid.

Just open the hood and look at the level of the brake oil can, as long as it is not lower than the lower limit.

When the level of brake fluid is not checked, brake fluid should not be added, so as not to add too much, and the brake oil will be sprayed to the high-temperature engine, resulting in corrosion and even combustion. If there are bubbles in the brake oil, or the oil becomes dirty, it means that the brake fluid has deteriorated, please replace it as soon as possible, so as not to reduce the boiling point of the brake fluid and produce bubbles, resulting in poor braking effect, which is very prone to danger.

"Idle instability is manifested as engine shaking and uneven revving when idling. The reasons for this are:

The idle air measuring hole is blocked, the idle device is not working well, the spark plug spark of individual cylinders is too weak, the individual valve is not tightly sealed, the intake manifold is leaking, the ignition time is too early or too late, and the idle speed adjustment is improper. When the engine idle speed is unstable, the idle speed should be adjusted first, if the fault cannot be eliminated after the idle speed adjustment, the idle speed measuring hole and the idle air measuring hole should be checked.

If the temperature of the combustion chamber is not reached, and the fuel combustion is not sufficient, it will be more obvious in winter, and there is no good solution.

Hello! Clean the throttle and check the spark plugs. No, you have to clean the intake manifold and the fuel system.

The car shakes at 1000 to 1500 rpmIdlingThe normal causes and workarounds are as follows:

1. 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. with a cylinder pressure gauge.

Check the cylinder pressure, and use Xinba to solve the fault of high pressure and low force. 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.

2. Carbon deposition. Grease blockage: throttle.

The idle valve and air intake hole will be blocked by carbon deposits, oil scale, and poor air intake, 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.

3. Fuel injector is blocked: 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 the gasoline has a rubber ruler, it will block the fuel injection hole of the fuel injector, so the fuel injection amount of 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.

4. The water temperature is abnormal: the engine working temperature has a normal range, and the water temperature will be high.

The ignition time becomes earlier, the oil-oil mixing ratio changes, the oil viscosity becomes thinner, and the lubrication performance deteriorates. The general cause of failure is the lack of antifreeze.

The shake caused by the thermostat not opening, the fan not turning, and the temperature of the temperature control switch is not accurate, the above troubleshooting can be solved.

5. 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 of the computer, some cars have adjusting screws on the throttle to adjust the idle speed, while some cars can not be adjusted, this kind of car can check the idle valve, throttle, air flow meter, vacuum degree Nian Zhen.

Sensors and adjustment of ignition time (for cars with distributors) can increase idling speed. Low idle speed can occur even when the water temperature is low, so you can check and replace the thermostat.
