2011 Ethereal 2 0 displacement, how to solve throttle lag?

In this car, the new car has a feeling of throttle lag, which may be related to its electronic throttle. The accelerator pedal of the electronic throttle is a "false throttle", just a receiver, after he receives the driver's action of stepping on the accelerator, it will transmit the power, amplitude and other data of the action to the control unit for analysis, and then summarize the driver's intention to step on the accelerator, and then the control unit controls the throttle motor to work according to the actual throttle opening and closing instruction after calculation.

Pulling the throttle is a little simpler, there is a "line" directly connected to the throttle valve of the pedal, how much you step on it, how much the throttle opens.

The electronic throttle can judge the driver's intention according to the details of the action amplitude of the accelerator, so as to achieve precise control, and its advantage is that it will be more fuel-efficient than pulling the throttle, smoother, and less prone to stalling and breaking. His disadvantage is that it is expensive, and secondly, it is delayed, and the response is not as fast as pulling the wire. Third, the structure is relatively complex, and there is a problem of failure rate.

The advantage of pulling the line throttle is to reflect the direct **cheap structure is very simple and basically will not be bad, the disadvantage is that the control is not accurate enough, a typical performance is that if the car with the pull line throttle has a small displacement and low idle speed, it is easy to turn off at the start, because your purely manual control of the throttle cannot be very accurate.

The effect of the electronic throttle and the cable throttle in actual use is actually good for the cable, because the reflection of the cable is direct, so there is a step on it, not like the electronic throttle to delay, Carnival is an example, very very fierce fierce. Some cars also insist on using the pull line throttle, because in some events where explosive power is emphasized, the electronic throttle loses 0A few seconds is basically the difference between victory and defeat.

But why is the electronic throttle good? The key is not the advantages listed above, but because the control of the electronic throttle is connected to the ECU and becomes a part of the electronic control of the whole car, and the pull line throttle is always free from the electronic control system of the whole car. The pull cord throttle cannot be installed with modules such as cruise control, which is its biggest problem.

If the throttle lag is very bad, it is best to go to the 4S store to show them, it should not be a big problem.

Hello: The problem you react to is not necessarily a failure, because this car is equipped with a Nissan MR2000 engine, and the total weight of this VQ2500 and VQ3500 is the same, so the engine power and torque must be less than and the amount of exhaust. As a result, there may be lag when you start with this car.

Another point is that this car is equipped with Nissan's new generation of CVT transmission, which realizes infinitely variable gears, and at low speeds, in order to maximize fuel economy, this transmission will lock the torque converter around 40 kilometers, and after the gear is locked, the driver may feel lag because all the power of the engine and transmission is transferred to the car. Of course, you can also go to the 4S store to check it out.

If the idle speed of the Ethereal engine is too high, then I think it should be necessary to reduce its speed, otherwise it may cause the temperature to be too high, and there may be no way to use it, so it should still need to be paid attention to.

The Nissan Teana engine has a high idle speed, which is basically an air leak. Check it out. Two steps.

1 Block the door of the solar term with the palm of your hand. There will be two cases. 1 (1) Engine stalled.

2) The engine does not turn off. If the engine stalls, the air leak is inside the throttle. If the flame is not extinguished, it means that the air leakage outside the air intake system needs to be further checked.

Now let's talk specifically about the air leakage in the throttle. Plugging the idle bypass vent in the throttle with your fingers, if the ignition is turned off, it means that there is a control problem with the idle motor system, and if the ignition is not turned off, it means that there is a gap in the throttle. There is a gap in the throttle valve that can be glued and sealed.

If there is a problem with the idle motor control system, you can use a fuel-saving idle motor to solve the problem, and whether there is carbon deposit in the throttle body and idle motor! It is recommended to clean the fuel circuit! Replace the spark plug.

If the idle speed value of the automobile engine is lower than or exceeds the specified range, there will be stage stalling and unstable speed. Today, we're going to take a look at the common faults of engine idling.

1. What should I do if the idle speed is unstable?

Idle instability is manifested as engine shaking and uneven speed when idling. The reasons for this are:

The idle air measuring hole is blocked, the idle device is not working well, the spark plug spark of individual cylinders is too weak, the individual valve is not tightly sealed, the intake manifold is leaking, the ignition time is too early or too late, and the idle speed adjustment is improper. When the engine idle speed is unstable, the idle speed should be adjusted first, if the fault can not be eliminated after the idle speed adjustment, the idle speed measuring hole and the idle air measuring hole should be checked whether it is blocked, if the measuring hole is blocked, it can be cleaned with gasoline or acetone and blown through with compressed air; If the measuring hole is not blocked, the engine speed should be stabilized at a certain speed, and whether there is air leakage in the intake manifold or carburetor or the lower gasket. If the idle speed is unstable and accompanied by the decrease of engine power, the working condition of the spark plug, the sealing performance of the valve and the ignition time should be further checked, and the maintenance and adjustment should be carried out if necessary.

2. How to identify bad idling?

A working engine should be able to run evenly in the speed range of 300-500r. If the minimum stable speed of the engine exceeds this speed range, or if the engine stalls and rotates unsteadily within this speed range, it is considered to have no idle speed or poor idle speed. When the idle speed is poor, it can be divided into idle flameout, unstable idle speed and high idle speed according to its fault characteristics.

If the engine works well from low speed to high speed after starting, but turns off immediately after releasing the accelerator pedal, or first runs unsteadily and then stops, it is an idle stall fault. If the engine is not running smoothly at idle, and the exhaust pipe makes a "suddenly, suddenly" sound, it is generally an unstable idle fault. If the minimum stable speed of the engine is higher than the specified range, and this speed cannot be reduced, it is too high idle or no idle failure.

3. How to adjust the idle speed?

Adjusting the idle speed must be carried out under normal conditions such as normal engine temperature, appropriate valve clearance, normal ignition system, good sealing of each pipe, full opening of choke valves, and tight closure of throttle valves. When adjusting, first unscrew the throttle opening adjustment screw to make the engine reach the lowest stable speed. Then use a screwdriver to screw in the idle adjustment screw, and when the engine is about to turn off, slowly unscrew the idle adjustment screw to make the engine run stably and reach high speed.

Then the throttle opening adjustment screw is screwed out to minimize the engine speed. Then adjust the idle speed adjustment screw to increase the engine speed. This is repeated until the throttle opening is minimal and the engine is running at the lowest stable speed.

Finally, increase the speed and close the throttle abruptly, so that the engine does not turn off.

Nissan Teana engine idle speed is too high, engine idle speed is too high, mainly check the gasoline injection pressure and air intake pipe leakage, you can first check the air intake pipe leakage, with carburetor cleaning agent in the position of each air intake pipe touch, to see if there is a phenomenon of speed increase? If there is, it is that part of the air leak.

The idle speed will be relatively high when it is just ignited, and it will return to normal after a while, so if the idle speed is high all the time, go to the repair shop to check it.

Hello dear, in 2010, Nissan liquid Tianlai displacement has three shortcomings: first, the fuel consumption on the suburban road is relatively high, and it may also be related to the road conditions here in my house, and the fuel consumption performance on the highway is better. Second, the paint of this car is relatively thin, and it is easy to have micro scratches, when I drove to a friend's house before, because there was a relatively narrow road, in order to avoid the car that did not come in front of me, I drove relatively to the side, and then the body was scratched by the branches of the tree to scratch out of the fine scratches, so I should avoid these branches as much as possible.

Third, although the engine is very strong, the CVT gearbox cannot withstand the frequent throttle, and the CVT is still relatively fragile and does not play the potential of this engine. To say that Nissan uses its own 7AT is perfect.

Summary. Hello, dear, the vehicle can not run uphill speed and jogging, it is recommended to check the following reasons for the failure:

First, the shaking or inability to speed up caused by carbon deposition in the vehicle engine, in this case, it is recommended to clean the carbon deposition in the throttle and intake tract, and then check the carbon deposition in the cylinder and whether the carbon deposition in the valve base is serious.

Second, the engine ignition system failure, this failure is generally caused by the ignition coil, or the aging of the spark plug, corresponding to the replacement of the damaged ignition coil, or the replacement of the spark plug.

Third, if the engine fuel system fails, the oil circuit is too dirty, or the fuel quality is too poor, it is recommended to clean the oil circuit, and then add some high-grade gasoline, or fuel treasure.

In the last case, it is considered that it is caused by the problem of the vehicle's gearbox, the internal friction plate of the gearbox is worn, or the solenoid valve body has been damaged, and the upshift is not timely or the acceleration is weak. The gearbox needs to be checked.

Dear, this question is up to me, it takes a little time to type, please be patient, thank you!

Hello, pro-Hongjian, the vehicle can not run uphill to speed up and jog this fault performance, it is recommended to check the following aspects of the fault causes: the first lead Zheng, the vehicle engine carbon deposition caused by the jitter or speed up weakness, in this case, it is recommended to clean the throttle and intake tract carbon deposits, and then check the carbon deposits in the cylinder, whether the valve base carbon deposits are serious. Second, the engine ignition system failure, this failure is generally caused by the ignition coil, or the aging of the spark plug, corresponding to the replacement of the damaged ignition coil, or the replacement of the spark plug.

Third, the engine fuel system failure, the oil circuit is too dirty, or the Huai Song is caused by poor fuel quality, it is recommended to clean up the oil circuit, and then add some high-grade gasoline, or fuel treasure. In the last case, it is considered that it is caused by the problem of the vehicle's gearbox, the internal friction plate of the gearbox is worn, or the solenoid valve body has been damaged, and the upshift is not timely or the acceleration is weak. The gearbox needs to be checked.

There is no need to adjust the idle speed when the cold car starts. The purpose of high idle speed of cold car is to make the engine run more smoothly in the low temperature climate, and when the coolant reaches the set temperature, the phenomenon of high idle speed will disappear naturally, so this is a very normal phenomenon and does not need to be solved by measures. In the case of high idling, it will reach about 1500 rpm, and after recovery, it will be between 600 and 800 rpm.

The idle speed of the vehicle is also a working state, in which the engine will idle, that is, the vehicle is in neutral. The speed at which the engine is idling is called idle speed, and this speed can be adjusted by adjusting the size of the damper, etc.

That is to say, when the engine is running normally, the driver releases the accelerator pedal completely, and the engine is in an idle state; However, it should be noted that when adjusting the idle speed, the speed can not be suddenly high or low, otherwise it will cause the engine to wear out early, which will greatly affect its life, so it is best to go to the automobile maintenance department for professional maintenance and adjustment.

That is to say, the speed of the engine is relatively high, and this phenomenon occurs if the speed of the car cannot run, this is a problem in the gearbox, this is a slippage in the gearbox, and it is possible that the transmission steel belt or the hydraulic cylinder inside has slipped. If this phenomenon occurs, you need to replace the gearbox oil, if it still doesn't work, you need to clean the solenoid valve in the gearbox, and you need to check the transmission steel belt in the gearbox, as well as the hydraulic cylinder in this one, to see if there is any slippage, which needs to be disassembled for inspection and maintenance.

Summary. Hello, this problem occurs, is the throttle injector is too dirty, the intake system is leaking, the air flow is damaged, the timing deviation and the oxygen sensor is damaged and the exhaust is blocked. There is a time limit for the first reply, if you have any questions, you can reply and answer them in detail.

Hello, this problem occurs, is the throttle injection hole is too dirty, the air intake system is leaking, the air opening family dry flow damage, timing deviation and oxygen sensor damage and exhaust blockage caused by the problem, you can clean the throttle first, the fuel injector after testing, fuel consumption is still high, Suiwu with a diagnostic instrument to observe the data flow of the above sensors, find the problem to replace the sensor on the line. There is a time limit for the first reply, if you have any questions, you can reply and answer them in detail.

Is it normal for 06 Teana to run 100 kilometers with 100 yuan of oil?

Abnormal, the fuel consumption is too high, the normal fuel consumption of this car is 6 cents per kilometer according to the current oil price.

There is no malfunction in the computer diagnosis.

Yes, if the computer reports the fault code, it will use the substitution value, and the fuel consumption will not become high, because the sensor has a problem, but it is still within the scope of the computer approval, and the computer will inject fuel according to the signal of the sensor, and the oil and orange rubber consumption will become higher.

Okay, you can.

There is a glitch. It's a matter of timing. When realigning, check the three places of the variable adjustment wheel for the intake air and the adjustment solenoid valve.

Does it also cost oil.

It will definitely cost oil, but if the time is not right, it will definitely cost oil.
