My Honda Civic idling was solid and shaky when I refueled up to 900 1000 rpm! What s going on? Ask f

My Honda Civic idling was solid and shaky when I refueled up to 900 1000 rpm! The car's idle motor is on top of the throttle cooker. It is mainly used to bear the idle speed of the car, and its purpose is to adjust the idle speed according to the engine load at the time of idling, and the idle jitter can check the pointer fluctuation of the idle speed meter, and the general performance is not good combustion, if it is a new car, there will be no problem of damage to the idle components, because the combustion requirements of the turbo direct injection vehicle are very engaged, or clean the oil circuit first, before the idle pointer fluctuation idle jitter in the fuel tank after adding the Si Youpu fuel additive to run two tanks of oil is completely good.

You need to go to a trusted repair shop near you or 4S to check it out.

Because based on the narrative alone, it's not very clear how to shake which part of the jitter and how much it shakes.

The feeling should be caused by the looseness of the power or transmission parts (such as the feet) or the main jitter parts, and the resonance of the vibration frequency during acceleration.

Of course, it could also be a computer problem or an air intake Fuel Injection Ignition One of the parts needs to be cleaned (sediment fouling, carbon fouling).

Just don't shake it when you drive it normally, but if it doesn't work, check it. Also, maybe you can't add oil.

Hello, this is normal, unless the Audi A8 is not shaking, the power is not good.

Hello, what you said about the engine shaking of the Civic cold car, is it normal in the case of a hot car, if it is just a cold car shake, then consider the throttle problem first, the throttle cleaning, or the oil problem. Hope to adopt.

Hello clean the throttle to check the gasoline pressure and see.

What to do if the Honda Civic gas throttle shakes, engine fault diagnosis generally has several situations, the most common reason for the severe formation of car flutter in the engine is the engine internal cleaning agent, which can remove carbon deposition and dismantle the engine oil to clean the carbon sludge, which is very convenient to use, and the suspension differentiation is not blocked, and the oil is miscible together and will not lead to delamination, better and safer cleaning of your engine.

The main reasons are:

1. The engine has serious 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 the presence of carbon deposits will affect the cold start.

Solution: Clean the oil circuit and check whether the idle motor has carbon deposits and should be cleaned.

2. Ignition system problems.

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.

Solution: Check whether the spark plug has too much carbon deposit, 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.

Solution: Check the oil pressure and replace the parts if necessary.

Civic refueling idle unstable It is possible that you have washed the throttle outside. Civic washed throttle needs the HDS system in the 4S shop to relearn to criticize idling, if it has not been washed, it should be possible that the throttle is too dirty

Idle jitter can view the pointer fluctuation of the idle speed meter, the general performance is not good combustion, if it is a new car, there will be no problem of damage to idle components, because the combustion requirements of the turbo direct injection vehicle are very engaged, or clean the oil circuit first, before the idle pointer fluctuation idle jitter in the fuel tank after adding Si Youpu fuel additives to run two tanks of oil is completely good.

Because the cold start is the time when the amount of fuel injection is the largest, the computer defaults to increase the fuel injection, but if the fuel injector exceeds the standard because of the colloidal impurities in the oil circuit, it will affect the fuel injection effect, and the mixer is not enough at this time, resulting in jitter. After the car is warmed, the computer reduces the amount of air intake and fuel injection, at this time the problem is not obvious, according to the phenomenon of reasoning, your car is actually after the hot car, there will be occasional idle shaking. Now it's summer and it's starting to shake like this, and it's even more severe in winter, so wash the oil circuit early to avoid greater damage to the vehicle.

This is a phenomenon of idle jitter, and the repair shop must detect the fault code after changing so many parts, and there must be no fault, indicating that there is no problem with the spark plug.

At this time, it is good to focus on checking the oil circuit problem. The oil circuit is not detectable, especially the dirty oil circuit will lead to poor combustion, idle speed because of the limited fuel injection will be more obvious, after the oil is sprayed with a large amount of oil to cover up this problem, the car will cost a lot more fuel than before.

The solution is also very simple, add 2 divisions to the fuel tank, and it will be significantly improved after running a tank of fuel. You can learn from it.

If the Honda Civic notices significant body shaking when starting or stopping the vehicle without turning off the engine, it may mean that the vehicle has the following four forms.

1.The engine has serious carbon accumulation and coarse slag.

The most common cause of car shaking is that the throttle bench is too dirty or the fuel injector is too much carbon. When the carbon deposit inside the engine is too much, the gasoline sprayed out by the cold start fuel injection head will be absorbed by the carbon deposit 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 the carbon deposit is saturated, it is easy to get on the car, and the gasoline adsorbed on the carbon deposit 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.

In addition, the lower the temperature, the greater the amount of oil required for the cold start, and the more the presence of 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 accumulation and replace the spark plug.

3.The oil pressure is unstable.

If you have cleaned the engine 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 the intake pressure sensor are normal. The solution is to check the oil pressure and replace the parts if necessary.

4.Aging of engine components.

Car jitter is also associated with aging of the engine feet. 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.

Summary. Hello, this is generally a car for a long time at low speed, resulting in too much carbon deposition in the engine, resulting in insufficient combustion, white smoke, engine shaking, weakened power, too high speed, sudden shutdown, etc., fuel consumption will also increase, it is recommended to clean the engine, throttle and spark plug, matching debugging, power will return to normal.

What is going on with the 1500 rpm shaking of the Honda Civic in 14 years The 1,500 ** motive shakes, and the big throttle does not shake.

Hello, this is generally a car for a long time at low speed, resulting in too much carbon deposition in the engine, resulting in insufficient combustion, white smoke, engine shaking, power weakening, high speed, sudden flameout, etc., fuel consumption base Li will also increase, it is recommended to clean the engine, throttle and spark plug, matching debugging, power will return to normal later.

1. The engine has serious carbon deposits, and the very common reason for car shaking is that the throttle valve is too dirty or the fuel injector has too much carbon deposit, clean the oil circuit, and check whether the idle motor has carbon deposits that should be cleaned. 2. If there is a problem with the ignition system, check whether the spark plug has too much carbon deposit, and replace the spark plug. 3. If the oil pressure is unstable, check the oil pressure and replace the parts if necessary.

Civic idle jitter causes and how to fix them are:

1. The engine has serious carbon deposits, and the very common reason for car shaking is that the throttle is too dirty or the fuel injector has too much carbon deposit. Solution: Clean the oil circuit and check whether the idle motor has carbon deposits and should be cleaned.

2. Ignition system problems, check the working conditions of spark plugs, high-voltage wires and ignition coils, the ignition system is not working well, and the spark plug jumping condition is not good, which will also lead to this kind of failure and cavity plexus phenomenon. Solution: Check whether the spark plug has too much carbon deposit, and replace the spark plug.

3. The oil pressure is unstable, if the engine carbon deposit has been cleaned, the throttle has been washed, the oil pad and spark plug have been replaced, etc., and the body is still found to shake when idling, it is recommended to go to the 4S shop to check whether the fuel supply pressure and the intake pressure sensor are normal, if the oil pump supply pressure is abnormal or the intake pressure sensor value is wrong and the poor work will cause the body to shake. Solution: Check the oil pressure and replace the parts if necessary.

4. The aging of engine parts and the shaking of the car are also related to the aging of the engine foot (also known as the claw pad). The engine foot is actually the shock absorption 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.
