What is the reason why the Jetta has a feeling of oil loss when driving

Regarding the analysis of the problem you mentioned, if you have just replaced the spark plugs, cylinder wires, ignition coils and fuel injectors, I wonder if the throttle of your vehicle is cleaned at the same time. Moreover, if there is too much carbon in the intake duct and valve, it will also cause the phenomenon of pinching the car, which is what you describe as having a feeling of oil failure. Now the EFI car is using the engine control computer fuel injection, in the high-speed driving hanging neutral engine will automatically cut off the fuel injection, only to maintain idle running, neutral sliding, the computer control unit forced to close the throttle to a small angle, because the throttle is too dirty, resulting in poor air intake, the vehicle will have the phenomenon of picking up the car.

In addition to the oil and throttle valves, during the engine braking process, the engine and body fixing bracket are too soft or the transmission differential gap is too large, which may cause the oil to be skimmed. However, the main cause of failure is due to poor contact of the clutch switch. Because the engine is controlled by ECU, the computer will continue to collect the clutch status, and control the amount of engine fuel injection when shifting, refueling, and resuming.

It is recommended that you regularly clean the throttle, fuel injector and intake tract every 2-30,000 kilometers of your vehicle, even if there is no failure, and check the combustion chamber and spark plugs for carbon deposits. Also check for failures in the various parts of all the above analyses.

Summary. There are three reasons: the use of low-quality gasoline can lead to insufficient combustion of the engine; clogged or clogged exhaust system; The injector is clogged or the injector is damaged, resulting in poor injection and poor atomization.

What is the reason for the slow oil collection in the driving of the old Jetta.

There are three reasons: the use of low-quality gasoline can lead to insufficient combustion of the engine; clogged or clogged exhaust system; The injector is clogged or the injector is damaged, resulting in poor injection and poor atomization.

In this case, you need to go to the auto repair shop to check it out.

That is, the throttle pin is slow after the accelerator is closed during driving, and there is no problem with oil.

The slow throttle response may be related to the gasoline you usually add. When we usually fill up gasoline, it is best to add a fixed number.

Jetta In normal driving, the reason for the stuttering when loosening the throttle and throttle: it may be that there is sludge in the transmission oil circulating in the gearbox to block the oil passage in the valve body, then there will be a problem of frustration, which will lead to a series of gearbox problems such as high temperature, impact, and slippage of the gearbox after a long time.

There are many reasons for the failure of oil harvesting, the most common is carbon deposit, hesitation for a long time at low speed, high-end driving, prone to this kind of situation. Secondly, the problem of the speed and speed sensors, and the analysis failure of the second sensor, will lead to a more obvious frustration in the oil shift.

Finally, there is the fuel supply, and the failure of the fuel injector and oil pump may lead to tight fuel injection, and there will also be a significant pause in the oil recovery shift. Of course, the throttle and ignition system, including the ignition coil, spark plug, ignition delay, and poor air intake may also cause a slash.

Mild frustration is normal, but more severe frustration may be the problem described above.

Under normal circumstances, there will be a sense of frustration when changing gears, so it is recommended that you drive as gently as possible when driving, and do not accelerate or brake too quickly.

Hello friends, Jetta car sometimes, refueling for a few seconds does not respond to the relevant reasons and how to deal with the following reasons. The first is the vehicle's careful throttle, the door is too dirty to cause this phenomenon, it is recommended to clean the throttle and the internal carbon deposits in the engine. The second is the problem of fuel circuit, it is recommended to replace the gasoline filter element, clean the oil and fuel injectors.

The third situation is that there is a problem with the brake light Xiangjin Heng switch, which is caused by this phenomenon, you need to check the brake light switch, and if there is a problem, you need to replace it with a new one. Summary.

Hello friends, Jetta car sometimes, refueling for a few seconds such as the clock does not respond to the relevant reasons and treatment methods are as follows. The first is the fuel saving of the vehicle, the door is too dirty to cause this phenomenon, it is recommended to clean the throttle and the carbon deposits inside the engine. The second is the problem of fuel circuit, it is recommended to replace the gasoline filter element, clean the oil circuit and spray the blind nozzle.

The third situation is that there is a problem with the brake light switch, which is caused by this phenomenon, you need to check the brake light switch, and if there is a problem, you need to replace it with a new one.

The car will rush to the gas pedal, in fact, it is frustrating to give the oil, what should I do? In fact, this kind of fault is very common, if the owner in the early stage of the failure to the repair shop or 4S shop maintenance, it is not a big problem, then we will take a look at the reason for the car gas pedal rush.

Car frustration is unavoidable, this manual transmission owner knows that if the accelerator and clutch do not cooperate well when changing gears, the vehicle will have a significant sudden deceleration and sudden acceleration, which is the most obvious "frustration". However, in automatic transmission, because the shift control is carried out by the computer, theoretically it will be smarter, but due to the structure of the transmission, in the automatic transmission model, the frustration is also different.

If the frustration of the car under normal conditions is excluded, first of all, we can do some simple checks by ourselves, such as whether the wrong oil is added, which is also possible, because with the addition of low-grade gasoline, there may be a situation of weak acceleration, resulting in a decrease in engine power and an increase in fuel consumption.

Then there is the engine oil system, which is not to mention the importance of oil, which can be fully lubricated, reduce resonance, and improve the smooth operation of the engine. If the oil is insufficient for a long time, the light one will have insufficient power and the fuel consumption will increaseIn the heavier case, the piston strikes the door, causing mechanical damage to the associated connectors. In addition, a faulty gasoline pump and a clogged fuel filter can also cause a drop in engine power.

It may be that the engine pawl glue or the gearbox pawl glue is damaged, which will cause the engine to shrug off the hole. The main function of the pawl glue is to absorb the vibration generated when the engine is working, to avoid the vibration from transmitting to the cab, once damaged, there will be a shrug when the oil is collected.

The second possibility is that the engine is under-intake caused by excessive carbon deposition on the throttle, which causes the engine to shake. It is also possible that there is a problem with the ignition system that causes the lack of a locust cylinder, such as a problem with the ignition coil that does not ignite, and the ignition is not smooth due to the service life of the spark plug reaching the limit.

Or the fuel supply system, the gasoline pump is caused by problems, such as the gasoline pump problem causes the oil pressure is not enough, the uneven amount of fuel injection in each cylinder leads to insufficient combustion, the carbon deposit clogs the fuel injector and causes no fuel injection, or the oil leakage of the fuel injector will lead to insufficient combustion, and the engine shakes the wheel. There was a problem with the gears inside the gearbox.

When the oil is lowered from high to low revs, poor gear connection inside the gearbox can also cause engine shake. (Photo by Chen Jie 2).
