Why does the car mourn when it is in gear and it is good to start it again after turning off the eng

The gears of the transmission are seriously worn: the transmission of the main car of the transmission can be divided into two types: manual transmission and automatic transmission, and off-gear driving is more likely to occur in off-gear driving. If the gears in the gearbox are worn, the locomotive will not be able to be transported, and the outer shaft of the gear will be particularly forced, and when the force is continuously greater than the force generated by the spring, it will cause the locomotive to automatically disgear.

Improper operation: The gear lever acts as one of the control operating systems in the car, controlling the speed of the entire vehicle, with driving force. Sometimes the vehicle is driving on a bumpy road, and the gear lever is not operated concretely, and the gears of the transmission cannot be coincidental, so it will slide out of the mesh.

Precautions: 1. The automatic transmission car can not slide, the manual transmission can slide in low gear, if the automatic transmission slides, the gearbox will be damaged, which needs to be noted, and secondly, the automatic transmission car can not brake on the left foot and the right foot throttle back, and the start can not be too fierce, and the throttle should be slowly given.

2. Automatic transmission cars are the same as manual transmissions, and they also need to change the transmission oil regularly, and when waiting for the red light, P gear can also be N gear, but the safest way is to step on the brakes.

3. The throttle should be given slowly when the automatic transmission car starts, and the throttle cannot be increased like the green light of the manual transmission car.

4. Automatic transmission cars are the same as manual transmission cars, and the transmission oil should be changed regularly.

5. When the automatic transmission car is waiting for a red light, you can either P or N or D all the time, but it is safer to step on the brake with your right foot.

Shifting refers to the fact that when the car is driving, the gear lever automatically returns to the neutral position, so that the sliding gear is out of the normal meshing position.

1. The positioning pin of the gear lever is worn loosely, broken or lost, so that it loses control and swings arbitrarily.

2. Abrasion failure of variable speed fork shaft interlock device; The gear lever ball joint is too worn or loose.

3. The gear, ring gear or sleeve is worn into a conical shape in the direction of the tooth length, and is out of gear due to the axial force generated during work.

4. The gear shift fork shaft chute, lock pin and other parts are too abrasive, and the fork is bent and deformed or the working face and the gear ring groove are abrasive.

5. The fixing nut at the rear end of the second shaft is loose, resulting in the axial channeling of the second shaft.

6. The locking pin of the synchronizer is loose or scattered, and the cone surface fails.

When it is found that there is a shift situation, it is necessary to check step by step according to the parts, and the solution is to repair or replace the new parts to solve these two sources of failure.

1. Due to improper operation, the clutch is not put well, and it is easy to stall when shifting;

2. When shifting gears during travel, if the operation specification still appears to be flameout, you need to check the following problems: first of all, see whether the idle speed is stable, if the idle speed is unstable or the idle speed is low, as long as the idle speed is adjusted to the normal speed. Also tighten the idle shut-off valve and plug it tightly.

Secondly, if the idle speed is normal, it may be that the oil-air separator is clogged and you need to go to a professional repair station to clean the oil-air separator. Solution to engine shake: a:

The engine shakes, pulls and pulls when refueling, and replaces the high-voltage line, but the problem has not been solved, and the engine is obviously shaking irregularly when idling, just like the engine is out of oil. What is the reason? b：

If it is a phenomenon of stopping before and after, it is basically a problem of circuit failure, and the problem should be investigated around the circuit part. If the engine is "weak" and causes shaking, the oil circuit, throttle, fuel injector, and combustion chamber should be cleaned.

It is estimated that the idle motor on the throttle valve needs to be cleaned or replaced, and the repairman also shakes the idle motor with his hand in front, and the result is immediately better, but the symptoms are not cured, and the broken or dirty ones need to be replaced and repaired. There is also a situation that the engine positive and empty pump is broken, which will also cause the rev to drop very low when the throttle is loosened and shifted, and then the engine will stall.

When the car starts, the engine of the car stalls when the P or N gear is shifted to another gear. Or if you hit the brakes while driving, the engine will stall!

If the engine stalls several times, then you need to check whether the impact of the lower gear is larger, if it is larger, then you need to take a first aid**. Otherwise, after many tests, it may just be a change of valve body, and in the end, it will become a change of gearbox overhaul!

Reasons for the engine stalling of the car:

Maybe the locking solenoid valve is damaged, or the locking control valve hairpin is damaged!

The idle speed is too low. The idle shut-off valve is not tightened.

The gear is too high. The oil-air separator was severely clogged.

How many gears are you hanging?

Ask a question: an empty car.

He doesn't show up often, just every now and then.

The separation is incomplete and problematic.

A common cause of stalling when a car shifts Idle speed is too low. The idle shut-off valve is not tightened. The gear is too high.

The oil-air separator was severely clogged. Stalling prevention and solution measures when the car shifts adjust the idle speed to normal speed. Check that the idle shut-off valve is tightened and the plug is tightened.

Shift into a lower gear. Clean the oil-air separator at a designated service station.

The idle speed is too low.

The idle shut-off valve is not tightened.

The gear is too high. The oil-air separator was severely clogged.

Stalling prevention and solution measures when the car shifts.

Adjust the idle speed to normal rpm.

Check that the idle shut-off valve is tightened and the plug is tightened.

Shift into a lower gear.

Clean the oil-air separator at a designated service station.

When changing gears while driving, if the operation is correct, the ignition will still appear, and the following problems need to be checked: First, look at the idle speed.

Whether it is stable in the state, if it is unstable, as long as the idle speed is adjusted to the normal speed. Even the idle shut-off valve.

It should also be tightened and plugged. If it is not normal, it may clog the oil-air separator, and a professional maintenance station will need to clean the oil-air separator.

Usually the reason why the car changes gears and stalls is as follows:

1. If there is no problem in operation, it should be that the speed in the idle state is too low.

2. If coasting in neutral.

There is often a stalling phenomenon, which can basically be judged as the engine idle speed is too low. Because there are many reasons for low engine idle.

3. Ablation of distributor contacts, insulation faults of cylinder wires, faults of distributor rotors, cylinder pressure drops, carburetors.

Improper adjustment and other reasons.

How do we solve this problem? Mastering the following techniques during manual shifting can avoid the occurrence of stalling during gear shifting. Next, let me talk about how to do it

1. Step on the clutch.

Fast, to be precise, release the clutch slowly, firmly, it depends on a lot of practice to strengthen the memory of the foot point.

3. The shift action should be coherent, if you can't hang up the clutch and then the clutch, you can hang it up (the general shift test operation time is 10 seconds, so don't worry about the lack of time).If the gear.

If it is not in place, do not clutch, so it is easy to shift and wear, and you can also listen to the sound of the engine to judge whether you can release the clutch.

4. Press the gear shift more during driving to avoid the car being suppressed, of course, if you are afraid of changing gears and operating more, if you make a mistake, then you can remember the gear you are hanging, control the speed of the car through the accelerator, and keep the match with the gear.

I believe that through the above analysis, car owners and friends will be more familiar with their vehicles.

When the vehicle is turned off, the main reasons are: the engine idle speed is too low; The idle shut-off valve is not tightened and the plug comes off.

Solution: Adjust the gear according to the vehicle situation to know the correct idle gear; If the plug with the idle shut-off valve or connection part falls off, simply plug it back in.

Because the speed is particularly fast when changing gears, and it is also because the clutch is not pressed when changing gears, it will cause the car to stall.

Because you don't change gears correctly while driving, the ignition will stall.

It is very likely that it is very unstable at idle, so be sure to check it, and if it is unstable, just adjust it to the normal speed.

What could be the cause of the vehicle stalling when changing gears?

1.Under normal circumstances, it is caused by the lack of tacit cooperation between the throttle and clutch. During shifting, if the operating specification still causes stalling, you need to check the following problems, first look at the idle speed.

Whether it is stable or not. If the idle speed is unstable or low, simply adjust the idle speed to normal speed. At the same time, tighten the start-stop valve and plug it tightly.

Secondly, if the idle speed is normal, the oil filter may become clogged and the car needs to be dismantled to repair and clean the gasoline filter. The clutch lifted after shifting gears and the throttle didn't keep up. When shifting gears, don't release the clutch too quickly or too violently, and keep up with the throttle in time to avoid stalling when shifting.

2.Master the following skills during manual gear shifting, and avoid shifting and stalling as much as possible; Step on the clutch quickly, once to the end, and slowly and steadily release the clutch, which requires a lot of practice to strengthen this memory band hidden point of the foot; To achieve the coordination of the throttle and clutch, hang one gear when starting, slowly release the clutch, refuel the valve in the semi-clutch state, and wait for the car to move before releasing all the clutches. It's still up to practice; The transfer action should be coherent.

If you can't shift gears, you can shift gears by releasing the clutch in neutral and then pressing the clutch again. If the gear is not in place, do not release the clutch, which is easy to wear out the gearbox.

gear, you can also listen to the sound of the engine to determine whether the clutch can be released.

3.During driving, the car should shift gears according to the speed of the car to avoid stalling. Of course, if you are afraid that the operation of the gear shift will make a mistake, then you should remember the gear you are in, control the speed through the throttle, and keep it in line with the gear.

Before manually shifting gears, the clutch must be pressed all the way down and then shifted. If the clutch is not stepped on, the gear lever does not pull, and the throttle is loose, then the engine stalls. See if the idle speed is stable.

If the idle speed is unstable or low, simply adjust the idle speed to normal speed. At the same time, tighten the start-stop valve and plug it tightly. If the idle speed is normal, the oil filter may be clogged and the car needs to repair and clean the gas filter.

The reasons for this are that the plug falls off, the idle stop valve is not tightened, the idle speed of the hidden motor is too low, it may also be a problem with the control, the possibility of engine computer failure is also relatively large, and the oil will bury the land bend to cause the cause of thin fruit bending, most of which come from the oil pump.

The gear is hung too high, the clutch operation is not standardized, and there is a problem with the fuel supply system, which may lead to the failure of the oil supply may lead to the stalling of the car with a virtual car.

Stepping on the clutch too hard, not stepping on the clutch to the end, when changing gears, the oil level and gear Lingru do not match, the shift of the clutch is not well controlled, and the clutch is put too fast when the ruler of the gear shift starts.

Stepping on the clutch too violently, the clutch is not stepped on to the end, the time of the virtual cavity shift, the oil level and the gear are not matched, the time difference between the gear shift is not well controlled, and the clutch is put too fast at the time of shifting.

It is likely that the gear and the speed of the vehicle do not match, and it may be because of the neutral slide, and it is possible that the lead is due to the brake and the high call, which may cause the vehicle to stall.

Because the idle speed of the engine is too low, the oil separator of the paint is blocked, and the vehicle will turn off, so I drove the car to the repair shop to let the pants leather maintenance master replace the engine. Hu Zai.

Hello, happy to answer your questions.

What causes the engine to stall when a car shifts?

Hello, happy to answer your questions.

Hello friend, when a car like you is changing gears, the engine stalls, and the reason for this is that there are many problems caused by dirty throttle, and you can clean the throttle. Clean the throttle and use the computer to match it after cleaning, friend. It is all when changing gears, which causes the idle speed to stall too low.
