Starting engine shaking is Premium trade data intelligence subscriptionsa problem that many car drivers will encounter. There are many reasons for engine shaking, which may be caused by the problem of the engine itself, or by damage to parts such as the battery or fuel injector.In this article, we will discuss the causes and solutions of starting engine shaking, and provide a solution to help car owners better understand and solve such problems. The reason for the shaking of the starting engine 1. The damaged air flowmeter is an indispensable part of the car engine. It can sense the size of the engine intake and transmit this data to the computer. If there is a problem with the air flowmeter, the engine will not be able to maintain the normal air-fuel ratio, and the engine may shake when starting. Two. Failure of the ignition system is one of the common causes of engine shaking. If there is a problem with your car ignition system, the car cannot produce normal sparks, causing the engine to abandon the normal working state, and the engine may shake.3. The fault of the accelerator pedal position sensor The accelerator pedal position sensor is an important component for measuring the position of the accelerator pedal. If there is a problem with the sensor, the car computer will not be able to correctly sense your trottle input, which may cause engine shaking. Four. Damage to the fuel injector is one of the key parts of the car engine, which ensures normal combustion by controlling the gasoline output. If the fuel injector is damaged and its output flow is unstable, it will cause the engine to shake when starting. How to solve the starting engine jitter 1. To check whether the air flow meter is damaged, you first need to verify whether the air flow meter is normal. If it fails, it is recommended to replace it immediately to ensure that the engine gets enough oxygen to maintain a normal air-fuel ratio. Two. To check the ignition system, you need to check whether the parts on the ignition system are faulty, such as wire swaps or spark plugs.In addition, make sure that the wires on the ignition system are firmly connected and not loose. If you find a problem with the ignition system, you need to repair or replace the relevant parts as soon as possible. 3. Check the accelerator pedal position sensor. If the engine shaking is caused by a failure of the accelerator pedal position sensor, it is recommended to replace it and make sure that the sensor wire is well connected. Four. Clean or replace the fuel injector. If the reason for the starting engine shaking is caused by the fuel injector, you can try to clean the fuel injector to remove the sediment. If the cleaning can't solve the problem, the fuel injector needs to be replaced. The first solution may have a wide range of causes of starting engine jitter, which is not conducive to the rapid location and solution of the problem. The first solution is to identify the cause of the failure through high-precision vehicle detection and accurately repair the fault according to the fault diagnosis.Automobile maintenance professional institutions are usually equipped with high-quality vehicle detection equipment, which can detect the reading of the engine control unit, diagnose possible fault points, and achieve one-time positioning and one-time repair, so as to quickly solve the starting engine jitter problem encountered by the owner. To sum up, starting engine shaking is a very common car problem, which may be caused by damage to multiple parts such as air flow meter, ignition system, accelerator pedal position sensor and fuel injector. In order to solve this problem, high-quality vehicle detection equipment has been introduced to achieve the purpose of one-time positioning and troubleshooting through the application of fault diagnosis, which is also a major advantage of modern automobile repair. Therefore, if there is a problem of engine shaking, the owner should detect and solve it in time to avoid the situation getting worse.
