VAZ-21124 jerks when overclocking: what's the problem?
What is the reason for the strange behavior of the car VAZ-21124 when overclocking and quiet driving, many car enthusiasts are interested in. Unexpected jerking on the ups and downs makes them worry about the technical condition of the vehicle. After all, no one wants to have problems on the roads, and God forbid that this deficiency became the root cause of the accident. Consider the most common reasons that can be directly or indirectly related to this problem.
Auto tweaks can be divided into three types:
- Twitching at the beginning of the car VAZ-21124;
- When driving, the machine twitches ;
- When overclocked.
To determine the causes of these faults, you may need special equipment that can be found in the service. However, practice shows that the reasons for jerking and twitching the machine can be a lot. And they may not necessarily be due to insufficient fuel in the fuel rail or a malfunction of the throttle position sensor .
Preventive actions are better than repair
But first of all, it is necessary to find the answer to the question of why the VAZ-21124 jerks when dispersing. In appearance, it seems, not an ordinary question. But in fact, it's not funny at all from such twitching. Especially eerie you start to feel when VAZ-21124 twitches at dispersal and the check lights up. Nuisance turned into reality.
It has long been known that any breakdown is easier to prevent than to eliminate. Therefore, try to pay more attention to your vehicle while driving. And here there is a problem: not every driver can feel the car and in time to determine this reason.
At once it is necessary to be defined with sequence of actions:
- It is unacceptable to check the car for jerking when driving at idle . This must be done only when driving.
- The check should begin at the most level and risk-free section of the road, where there is no rapid traffic.
- To check, start in turn to carry out the gear shift by pressing on each of them on the gas pedal.
- If the vehicle starts to twitch without your participation, therefore, the root cause of the problem should be sought in this problem.
Causes
Why does the VAZ-21124 twitch when it is overclocked? You started checking, increasing the speed, and the car starts to shake and twitch.
Her move has lost smoothness. What is the problem? In the unstable supply of auto fuel. In other words, it arrives there periodically. Since the fuel pump in the car gives a gasoline pump, then, most likely, you need to look in it.
How to cure the machine?
To begin with, it is necessary to diagnose the gasoline pump:
- Remove the lid from it and visually inspect visually, focusing on the place near the valve;
- If there is no O-ring, take corrective action.
In this case there was a depressurization of the gasoline pump, and started to occur interruptions with fuel supply. This is the reason for the malfunction of the car. After restoring the tightness of the car VAZ-21124 (16 valves) will again smoothly move along the road. The replacement of the sealing ring can be carried out independently, the main thing is to find the right ring and tools.
Problems at low speeds
Consider twitching at low speeds. In case the VAZ-21124 jerks when accelerating at low rpm, it is necessary to diagnose the performance of the injector and harness. If it is located on the fuel pipe, there is a possibility that it could be damaged, which can cause a short circuit of the wiring and shutting off the injectors. The solution of the issue is a complete replacement of the wiring. Do not ignore this problem, because it can lead to great trouble.
Twitch auto - check the spark
Often, a car's malfunction is associated with the formation of a spark, and therefore begins to behave strangely.
It is easiest to determine this problem when descending from a hill or on a fairly flat area. To prevent this, you need to check the candles (VAZ-21124). In case of failure, overheating or unstable operation - replace. The price of candles (VAZ-21124) is about 700 rubles per set.
So, what are your actions if the car starts to twitch when you press the gas. In order to fix the problem, you must first find it. For example, if the car drives gas, the problem can be covered in a vacuum regulator.
Where is this part located?
It is located on the toggle switch. If a damaged regulator is detected, the replacement of the carburetor will not help either. Most likely, the replacement of the regulator will help to eliminate the problem.
The next culprit of periodic jerking of the car can be a nebulizer of the accelerator pump. To prevent damage, remove the diffusers and press the lever to evaluate the operation of the pump in each of the chambers. If at least one of them is experiencing unstable work - this is the reason why the VAZ-21124 jerks when driving. A complete removal of the sprayer for cleaning and blowing it will help to solve this problem. After the procedure, the cleaned part should be installed back. If this was the main cause of the car jerking, then the problem is solved.
VAZ-21124 twitches when it disperses. This may be a diaphragm fault
To such jolts can provoke an insufficient amount of fuel, which is caused by the most elementary clogs of fuel filters.
To determine the technical condition of the filters, you have to disconnect the rubber hose and blow the mesh.
When doing this, do not forget that the fuel tank cap must be removed.
After a certain time, the procedure should be repeated, and the washing of the fuel tank must be added to the cleaning of the filter. These actions will help to avoid the next clogging and prolong the life of the filter. If the cause is not eliminated, and the car is still twitching - pay attention to the fine filter. You may even have to replace it with a new one. For unhindered fuel flow into the tank it is necessary to fill it with the specified part and start the power unit. For this, it is necessary to replace the fuel hose with the radiating tube and begin to pump the liquid into the filter. In conclusion, install all the parts back and take a few clicks on the hand pump. Only after the engine engine it is possible to fully test its operation. Performing this action facilitates the rapid filling of the filter with fuel.
Actions of the driver in the case of car jerking in a carburetor engine
The causes of jerking are auto - obsolete fine filters. If the indicated problem happened to you on the way, then the best way is to contact the auto repair shop. The best way out of this situation will be their replacement.
The reason for the twitching is the control unit
The supposed cause of the shocks lies in the gear shift. To understand the essence of jerking is difficult enough.
Therefore, if you notice that the VAZ-21124 jerks during acceleration or driving - it is better to go to the car repair shop for diagnosis. In the autocenter, it's easy to help determine the cause, because the lift is much easier to see the problem. The movement of the car at idle allows us to understand not only why the car constantly pushes, but also to track the smoothness of the revolutions. Sometimes this problem is much more complicated than it seems, and for its detection it will be necessary to create special operating conditions, which is completely unrealistic to perform while driving.
Twitching the machine with the engine running normally
This signals that the engine is defective, and the problem lies in the other. In this case, check the following:
- Reliability of fastening of the power unit;
- Checking integrity counters;
- Durability of screwing the wheels.
If the problem is not found - will have to look for experts to carry out the diagnosis and for some time to stop driving on the car.
conclusions
As can be seen from the above, there are quite a few reasons for jerking the machine during its operation.
And you do not need to be an expert in automotive matters. Minor breakages in his car should be repaired by anyone. If you notice the strange behavior of the car, including jerking with jerks, you should always consult a car service center or ask automobile professionals who have more than one year of practice behind them.
