The car idling shakes from time to time, what is the problem of the car idling shaking

Main causes of idle jitter:

1.Serious engine carbon deposits: Cars always have the problem of carbon deposits, including cylinder carbon deposits, throttle carbon deposits, spark plug carbon deposits, intake carbon deposits, etc.

When the engine has too much carbon deposit, it will affect the ignition energy, air intake efficiency and air-fuel ratio of the car, resulting in the unstable power output of the car, and the phenomenon of idle speed and acceleration jitter appears.

2.Unstable oil pressure: If you have cleaned the engine carbon deposits, cleaned the throttle, replaced the oil gasket and spark plug, etc.

And when idling, you still find that the body shakes, it is recommended that you go to the 4S shop to check whether the oil 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, it will cause the body to shake.

3.Engine cylinder shortage: Engine cylinder deficiency mainly refers to the engine one or more cylinders are not working properly, which is generally manifested as:

The exhaust fumes coming out of the car are obviously intermittent, and the exhaust pipe shakes violently, and the engine shake can be clearly felt, sometimes accompanied by abnormal noises. This is mostly related to ignition coil failure.

4.Aging of engine parts: Shake in the car is also associated with the 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 engine base, these vibrations can be transmitted to the steering wheel and cab, causing vibrations at idle.

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.

I believe that many car owners and friends have encountered the car idling from time to time to shake, many car owners do not think so, so let's see what the problem is with the car idling jitter.

First of all, the idle shake of the car can not be taken lightly, the causes of idle shake are serious engine carbon deposits, ignition system problems, unstable oil pressure, aging engine parts, etc., let's take a look at several common problems.

The engine has a lot of carbon deposits

Engine carbon depositsI believe that many old drivers know that if there is too much carbon in the engine, the vehicle will have poor engine working condition, high fuel consumption and even difficult starting, which will cause greater damage to the vehicle over time.

The carbon accumulation of the engine is caused by our daily driving habits, such as long-term idling, slamming on the accelerator and braking, poor oil quality, high-end and low-speed driving, and no regular maintenance.

There was a problem with the ignition system

When some components of the ignition coil of the arc system of the automobile or the circuit are broken or short-circuited, the primary current is too small, the secondary voltage is too low, and the ignition adjustment fails in advance, it will lead to the unstable state of engine operation, which will make its acceleration performance deteriorate, the power and fuel economy will deteriorate, and the problem of idle jitter will also occur.

The oil pressure is unstable

There are many factors that cause unstable engine oil pressure, such as lack of oil, dirty oil, thinning of oil, leakage of oil pipes, damage to the oil pump or excessive wear of its parts, etc. It is worth mentioning that if the engine continues to run under the condition that the oil pressure is too low, the situation may cause the engine to "burn the tile", and the engine will not start at this time, and the tile needs to be scraped or replaced.

In addition to the reasons mentioned, there must be other factors that cause car idling and shaking, and it is recommended that car owners do not think that car shaking is a trivial matter, and it is quite fatal when it is serious.

Is it normal for a new car to have a slight shake at idle is it normal for a new car to shake its engine at idle is it normal for a new car to shake its exhaust pipe at idle speed is it normal for a new car to shake a little bit at idle speed is it normal for a new car to have a little jitter at idle How to tell if it is normal for a new car to idle and shake.

The car idles and shakes, these 3 points tell you the reason, and learn to avoid being pitted.

It is also common for the car to shake occasionally while idling. There are a variety of reasons for this, such as ignition system issues, excessive carbon build-up in fuel injectors, engine aging, etc. Hope it helps. Hope to adopt!

Hello: There are several reasons for engine shake: Low speed:

The engine idle speed value is set in the computer, and when the speed 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.

Hope it helps!

There are several possibilities for engine shake.

1."The air filter is dirty, clogged, and not replaced in time, or the high-voltage line is broken and affects the ignition and causes the engine to shake.

2.Engine shake caused by spark plugs not being replaced in time or low fuel pressure.

3.Dirty throttle valves, clogged injectors, or low cylinder pressure can cause engine jolting.

The car shakes from time to time when idling, probably because: 1. The carbon deposit in the engine is serious. It can be said that as long as you drive, there will be carbon deposits, such as long-term idling, slamming on the accelerator and braking, and poor oil quality, which will cause carbon deposits to increase.

There is a problem with the fuel injector, which causes the gasoline to atomize poorly. Solution: Clean or replace the fuel injector.

Throttle blockage. Solution: You can try to clean the throttle first and see if the problem can be solved. If not, you can only replace the throttle.

The oil pressure is unstable. Lack of oil, dirty oil, and thinning of the oil will all lead to unstable oil pressure.

There are many reasons why a car shakes from time to time when it idles. Basically, if there is a problem in any part of the fuel system, air intake system, and ignition system, it may cause the car to shake from time to time when idling.

For example, insufficient air intake, spark plug failure, changes in the amount of fuel injected in the car, carbon in the surface area of the oxygen sensor, etc.

Since you can't see the actual car, you can't make an accurate judgment. The specific cause can only be determined after an inspection by the staff. It is recommended to go to a 4S shop or a professional auto repair shop in time to let the staff check it, and only by determining where the problem is, can the symptoms be repaired.

The possible reasons are bad fuel oil, dirty throttle, excessive carbon deposition inside the engine, etc., according to the subject's description, it may be a problem of carbon deposition inside the engine.

Clean the idle motor and throttle.

Use a computer to read the data stream to see if there is an occasional lack of cylinders.

1.The ignition electronic system is unstable and the mating is not secure.

2.Loose wiring or carbon build-up in spark plugs.

My car is idling and shaking, what is going on with everything else normal It's okay to be a little normal, but don't do it for a long time, this will cause serious carbon accumulation in the long term, resulting in a decline in engine performance. It is best to adapt to 10,000 kilometers at a time, and there are *-pu such detergents and fuel additives, so that it will be very clean and not black.

I believe that many car owners and friends have encountered the situation of car idling and shaking when driving, and many car owners do not agree. So let's take a look at the problem of car idle jitter. First of all, car idle jitter cannot be ignored.

The causes of idle jitter include serious carbon deposits in the engine, problems with the ignition system, unstable oil pressure, aging engine components, etc. Next, let's look at some common questions. The engine has a lot of carbon deposits

Engine carbon deposition I believe that many old drivers know that if the engine carbon deposition is too much, the vehicle will have poor engine condition, increased fuel consumption, and even difficult to start symptoms, which will cause great damage to the vehicle over time. Engine carbon deposition is a bad habit of our daily driving, such as long-term idling, slamming on the accelerator and brake, poor oil quality, high-end and low-speed driving, irregular maintenance, etc. There is a problem with the ignition system.

When some components or circuits of the ignition coil of the automobile arc system are open or short-circuited, the primary current is too low, the secondary voltage is too low, and the ignition adjustment fails in advance, the engine will run in an unstable state, which will make its acceleration performance, power performance and fuel economy worse, and will also cause the problem of idle jitter. There are many factors that cause unstable oil pressure, such as lack of oil, dirty oil, thin oil, oil pipe leakage, oil pump damage or excessive wear of its parts. It is worth mentioning that if the engine continues to run at low oil pressure, it may cause the engine to be severe in severe cases""Burning tiles" at this time the engine will not start, and the tiles need to be scraped or replaced.

In addition to these reasons mentioned by Bian Xiao, there must be other factors that cause the car to idle and shake. Here it is recommended that car owners do not think that car shaking is a trivial matter, and it is quite fatal when it is serious.

Shake the car from time to time when idling, and the car shakes from time to time when idling, which may be due to serious carbon deposits in the engine. It can be said that as long as you drive, there will be carbon deposits, such as idling for a long time, slamming on the accelerator and brakes, poor oil quality, etc. , all of which increase carbon deposition.

2.There is a problem with the injector, which causes the gasoline to atomize poorly. Workaround:

Clean or replace the injectors. 3.The throttle is blocked.

Solution: Try cleaning the throttle first and see if the problem can be solved. If not, the throttle can only be replaced.

4.The oil pressure is unstable. Lack of oil, dirty oil, thin oil, etc.

It will lead to unstable oil pressure. There can be many reasons why a car is shaking at idle speed from time to time. Basically, if there is a problem with any part of the fuel system, air intake system, and ignition system, it can cause the car to shake from time to time while idling.

For example, insufficient air intake, spark plug failure, changes in car fuel injection, oxygen sensor surface area carbon, etc. I can't make an accurate judgment because I can't see the real car. The specific reason needs to be determined by the staff inspection.

It is recommended to go to a 4S shop or a professional auto repair shop in time for the staff to check. Symptoms can only be fixed if the problem is determined.
