What is the reason for the car to stall at low speed The spark plug and idle motor have been replace

1. In fact, whether the spark plug needs to be replaced, remove it and check it to see if the color of the burning, the gap between the electrode, the gap between the porcelain body and the metal shell, etc. If you find that it is difficult to start the car in a cold state, there is obvious frustration when driving, idle shaking, or the engine acceleration performance is reduced, you should check the spark plug in time. Because once the vehicle has the above performance, it may be caused by the aging of the spark plug.

Second, car maintenance is very troublesome, when the car travels to a certain number of kilometers, the spark plug will produce carbon deposition electrode gap will also increase, carbon deposition will increase engine fuel consumption, and the increase of spark plug gap will cause difficulty in starting. Therefore, frequent inspection and maintenance of spark plugs can prolong the life of the engine.

Third, to do maintenance:

1. The air filter should be cleaned regularly to avoid dust from entering and burning with the mixture, which can prevent the spark plug from corroding.

2. You can also remove the spark plug by yourself to clean up the dirt and carbon deposits on the ignition head. However, it is particularly important to note that when disassembling and assembling the spark plug, it is necessary to pay attention to the spark plug in and out, pay attention not to let dust enter the cylinder, and clean the surroundings when disassembling the spark plug in advance. If there is organic oil in the cylinder, the piston ring or other parts should be replaced in time to avoid the short circuit of the electrode caused by carbon deposition in the spark plug.

Hello, I am happy to serve you and give you the following answers: The solutions and practices for replacing the spark plug idle flameout are as follows:1

First of all, disassemble the spark plug, check the wear degree of the spark plug, if the spark plug is badly worn, you need to replace it with a new one. 2.When changing the cover pin for a new spark plug, pay attention to check whether the thread of the spark plug is damaged, if it is damaged, you need to replace the spark plug thread with a new one.

3.When installing a new spark plug, pay attention to check the installation depth of the spark plug to ensure that the spark plug installation depth is correct, so as not to affect the normal operation of the spark plug. 4.

After the installation is completed, it is necessary to check whether the connection of the spark plug is firm, and whether the spark of the spark plug is normal, so as to ensure the normal operation of the spark plug. Personal tip: When replacing the spark plug, pay attention to check the wear degree of the spark plug, as well as whether the installation depth and connection of the spark plug are firm, and whether the spark of the spark plug is normal to ensure that the spark plug works properly.

Hello, happy to answer your <>

The EFI pedal has replaced the spark plug and idle motor, cleaned the throttle valve, and the reasons why the engine will still stall without oil after the cold car starts: the fuel route is blocked, the air flow meter is faulty, and the engine control unit ECU is faulty. The above is the reason why the EFI pedal has been replaced with a spark plug and an idle motor, and the throttle valve has been cleaned.

The EFI pedal has been replaced with a spark plug and an idle motor, and the throttle valve has been cleaned.

Hello, I'm glad that Yin Xiaoxian will answer for you the reasons why the EFI pedal has changed the spark plug and idle motor, cleaned the throttle valve, and the cold car will still stall without oil after starting: the fuel route is blocked, the air flow meter is faulty, and the engine control unit ECU is faulty. The above is the reason why the EFI pedal has replaced the spark plug and idle motor, cleaned the throttle valve, and the cold car will still stall without oil after the cold car is started cautiously.

The motorcycle fault light is not on. In the morning, the first start can be started normally without oil, and after the start, the idle speed will be automatically extinguished after six or seven seconds, and then the second start needs to be started with oil, and the engine will be extinguished without oil. When driving cold, you must carry oil at idle, otherwise it will turn off.

Zhipei will not turn off when the hot car of Qingtong is idling. During the hot car driving, after the oil is carried out, the idle speed will occasionally turn off in the oil return state.

The viscosity of the lubricating oil increases, the fluidity deteriorates slowly, the engine starting resistance increases, the viscosity of the electrolyte in the battery increases, the fluidity and diffusion deteriorate, the air filter is not in good condition and the quality is not up to standard, the impurities in the air may enter the combustion chamber, the valve clearance is too small, it will cause the engine to leak in the process of compression and workmanship, the motorcycle cylinder pressure is low, the valve seal is not tight, the piston ring is worn, and the cylinder is worn. Low carburetor oil levels and too thin mixtures can cause problems with the cold start of the motorcycle.

Do you mean that there might be a problem with the valve clearance?

What the teacher said above will cause you to do that.

After seven or eight seconds, it was back to normal operation.

In your case, the throttle cable is not returned, and the lubrication is not enough.
