Why does my car jerk while accelerating? 

/by

We always foresee our Car to run very well, especially when we buy it new. On the other hand, Car is like a Human. The older it gets, it’s also increasing in serious problems. The most common issue is a Car jerking and it’s a signal that you should be mindful of. 

If you are curious why your Car is jerking, stutters when it is accelerated, it might be because of insufficient air, fuel, or a defective spark plug.

Most importantly, let us find out what are the causes and how to solve all the issues.

 

  • Greasy Fuel Injectors 

 

  • The most important thing is to always clean the car’s injectors to avoid car stutters or jerks.
  • Uncleaned injectors can be 1 of the main reasons your car will lose its power and jerk while you are using or driving it. From an unstable fuel consumption, there will be an engine stutter.
  • You can use the high-quality injector cleaner but the best thing to do is clean the injector manually or replace a new one.
  1. Clogged Catalytic Converter 
  • The important role of a catalytic converter is to decrease the extent of the pollutants that are coming out from a Car’s exhaust. By the time the air or fuel mixes in the Car’s engine, it can develop a clog in the catalytic converter and lead to disrupting the airflow from the exhaust system.
  • A clogged catalytic converter can lead to jerking, stuttering, and as well as downtime. It can result in stuttering, jerking, and an overall delay in reactiveness when you step on the gas.
  • Moreover, a catalytic converter cleaner might help, on the other hand, if it does not work then visit the nearest repair shop or you should change to a new catalytic converter.
  1. Defective Mass Air Flow Sensor 
  • The main function of the Mass Airflow Sensor is to determine the quantity of air that enters the engine that the computer box reads to modify the ratio between fuel and air.
  • A Car may experience low power, poor acceleration, high fuel consumption. Also, it can surprisingly jerk the car if driving at a higher speed.
  1. Malfunctioned Spark Plugs 
  • The standard source of the problem is also the simplest to distinguish and repair. To accurately ignite the fuel, we need a good spark during the process of combustion.
  • It will cause the engine to break down if the spark plug is uncleaned.
  • The cheapest and easiest way to repair this kind of issue. The answer to the solution is to change the spark plugs.
  1. Water or Liquid build-up in the Distributor Cap 
  • The most reason why water or liquid can form is due to damage or hairline cracks.
  • In addition, the moisture will cause electrical failure in the spark plug connections or terminals.
  • Just make sure to check or inspect the distributor Cap then you can get rid of the moisture if you will cover your Car with thermal covering.
  • You can also spray W-40 to prevent moisture.
