The main cause of idle jitter;
1. The most common cause of vehicle shaking is that the throttle is too dirty or the fuel injector has too much carbon.
2. When the carbon deposition inside the engine is too much, the gasoline sprayed by the cold start fuel injector will be absorbed by a large amount of carbon deposition, 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 started, 3. After the car is adsorbed, the gasoline adsorbed on the carbon deposition 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, resulting in 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.
Severe idle vibration is generally caused by engine cylinder failure, aging or loose foot rubber, carbon deposits, fuel system failure, etc.
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.

1. It may be that the engine is running unsteadily and the carbon is cleaned.
2. Check whether the steering wheel is shaken, whether the heat exhaust fan is loose or problematic, and there is the ball dragon and ball head, you should check the four-wheel alignment after replacement, otherwise you will not be able to hang the gear.
3. Check the engine rubber pad.
Check whether the engine gasket and air conditioning compressor are loose.
4. If the idle speed is too low, it may be that the engine cannot receive the air conditioner opening signal, or it may be that the engine speed cannot be increased due to the weak voltage of the air conditioning opening signal, and the engine shakes due to heavy load.

What is the cause of engine shake when the 11 Ford Fiesta is idling, and the engine intermittent idle shake is generally not a problem with accessories, but from poor combustion, which will cause such a phenomenon. The oil circuit can be cleaned, and the gas station also regularly cleans the oil storage tank, not to mention the fuel tank of the private car. The oil circuit of the fuel tank is dirty, and if it burns badly, it will miss the post and catch fire.

Causes of unstable car idling;
Throttle oil and throttle carbon deposits, dirty intakes, blocked intakes can cause idle pulling, throttle carbon deposits or oil are the most common causes of unstable idling.
Spark Plug Failure: Weak sparks caused by individual spark plug failures can also cause carbon deposits, which can be cleaned to restore spark plug activity, but some spark plugs have a fast lifespan and can reduce performance.
Blocked oil circuits: There are also oil circuit blockages and intake pipe failures represented by fuel injectors. When the oil circuit represented by the injector is blocked, the fuel supply pressure is insufficient, the fuel atomization is poor, the mixing ratio is unbalanced, and the combustion is incomplete, which leads to the failure of Changying return.
Specific solutions to idle jitter:
1. The engine has serious carbon deposits. The most common cause of idle judder is excessive carbon build-up on the throttle or injector. When there is too much carbon deposit inside the engine, the gasoline sprayed by the fuel injector during cold start will be absorbed by the carbon deposit, resulting in a mixture that is too thin and making it difficult to start.
After landing, the gasoline adsorbed on the carbon deposits will be sucked into the cylinder by the engine and burned, which will thicken the mixture. The mixture is sometimes dilute and sometimes thick, which will cause idle jitter after cold start. The lower the temperature, the greater the amount of oil required for cold starts, and the more the presence of carbon deposits affects cold starts.
The solution is to clean the carbon deposits at the throttle and injector.
2. Poor ignition system and poor ignition of spark plugs will also lead to engine idling and shaking. If there is a problem, check if the ignition system is faulty and if there is too much carbon deposited in the spark plug.
3. The oil pressure is unstable. If you have cleaned the engine carbon deposits, cleaned the throttle valve or replaced the spark plug, and there is still the problem of body shaking when idling, it is recommended to 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 is incorrect, it will also cause the body to shake when idling.
Solution; The best way is to clean the oil circuit, clean it regularly, there is no specific experience in the research and development parameters of the clean engine from the new car, coupled with the continuous improvement of emission standards, can not adapt to the change of fuel, all manufacturers of the engine are unable to solve this jitter problem in the short term, plus the fuel quality is not very good or the initial fuel of the new car factory 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. The occurrence of carbon deposits exceeding the hunger resistance standard is especially common for China VI vehicles. We can only gradually alleviate most of the problems by maintaining clean oil circuits. The use of PNF dope fuel additives can solve the problems caused by carbon deposition.

The main reasons for the phenomenon of car engine shaking, unstable idling, inability to refuel, inability to hit the car, and failure to start the engine are as follows:
1. The battery voltage of the car is low; Detection method of failure: test the battery voltage with the voltage level of the three-purpose meter, if it is below 10V, it is recommended to replace it. It is like about 11v, and it is barely used; Be prepared for replacement.
Above 12v can be used, but other reasons need to be found;
2. Check whether it is caused by carbon deposits; If you travel about 20,000 km, focus on checking and cleaning the throttle;
3. Inspect, test and replace spark plugs;
4. Confirm the quality of the gasoline added;
5. Detecting the ignition switch;
6. Test and detect the starter, gasoline pump, sensor and other related components of the starting and oil supply system;
7. After powering on, do not start immediately, wait for 30 seconds to 1 minute, and then ignite; See if it works;
Regardless of any of the above situations, pay attention to the time when the car cannot be hit once, be sure to play again after an interval of 15-30 seconds, in order to protect the battery but not to generate the power dispatch key and prolong its service life.

If there is a problem with the spark plug, replace the ** fitting. If you can confirm that the spark plug is**, you can try to change the high-voltage wire and ignition coil.
-
Clean the throttle, idle motor, spark plug and spray repentance nozzle, generally can be eliminated, if it still doesn't work, it is recommended to go to the 4S shop eggplant to further check the ignition timing, cylinder pressure, etc.

Can the water temperature sensor be powered off when it is powered off?
If the water temperature sensor is unplugged, it will not affect the start of the vehicle, and the vehicle can start normally. However, the water temperature sensor is an important parameter when the engine is started. If there is a problem, the on-board computer will default to low temperature, which will increase the fuel injection of the engine and collapse and ignition in advance, which is a kind of damage to the engine.
The engine is the heart of the car, and the water temperature sensor is the instrument that senses the problem, so it is not always important for the engine. Although it is not plugged in or has a problem, it will not affect the normal start of the car, but its problem will make the driving computer make a wrong and clever judgment, thinking that the outside is low, which will increase the workload of starting, and is harmful to the operation of the engine and the efficiency of the engine. Therefore, the vehicle must be regularly maintained to ensure that there are no safety hazards, I hope mine can help you!

Causes of jitter:
1. The oil pressure is unstable, such as Qi Acorn has cleaned the engine carbon deposits, 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, if the oil pump supply pressure is abnormal or the intake pressure sensor value is wrong and the work is poor, the body will shake;
2. The engine has serious carbon deposits, and the most common reason for car shaking is that the throttle valve is too dirty or the fuel injector is too much carbon. When the carbon deposition inside the engine is excessive, the gasoline sprayed by the cold start fuel injection head 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 started, and the gasoline adsorbed on the carbon deposition after landing 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 sometimes thick, causing idle shaking after cold start;
3. The lower the temperature, the greater the amount of oil required for the cold start, and the more the carbon deposit will affect the smooth or not of the cold start.
