In most cases, trying to figure out why your car is jerking when driving isn't always straightforward. Generally, jerking during acceleration indicates that the car will develop some other problem if the issue is not addressed. Hence, it could leave you with a lot of guesswork about where to begin to identify the source of the problem. Below are some basic reasons that could lead to a car jerking as you pick up speed and how to fix the issue.

Dirty Air Filters

Your air filter should be as clean as possible for a smooth ride. That said, as you drive, it becomes clogged with dirt particles and debris from the air. So, if you experience jerking during acceleration, check the condition of your air filter and have it replaced. In essence, the best course of action is periodic replacement anytime you visit your mechanic to perform the normal engine service for your car. 

Clogged Fuel Injectors

Fuel injection into the engine system is an essential component of the overall performance of your vehicle. Further, the fuel injected should be as refined as possible and free from dirt for optimal performance. However, as it courses through the lines into the engine system, it often leaves the fuel injectors dirty and full of debris. This affects their ability to function, which in turn controls how your vehicle accelerates. Moreover, problematic fuel injectors limit the flow of fuel and, thus, affect acceleration. To correct this, visit a mechanic and have the injectors cleaned to free them from any dirt. 

Problematic Spark Plugs 

Your spark plugs must be in the best shape possible to avoid power shortages throughout the vehicle. In addition, they ensure efficient fuel combustion to give your vehicle maximum torque power during acceleration. However, if these components are worn out, replace them immediately to stop jerking during acceleration. Also, during normal engine service, your mechanic can check the status of the spark plugs. If necessary, have the auto expert replace them to avoid problematic plugs when in transit. 

Worn-out Catalytic Converters

Regular car use often leads to wear and breakdown of the catalytic converters. So, if this is the case, you need an auto mechanic to repair blockages. Note that your vehicle should pick up the normal acceleration speed after unclogging the converter. However, if it fails after unclogging, have the entire catalytic converter replaced.  

Additional factors to check if you experience jerking on acceleration include carburetors, acceleration cables, gas lines, and cylinder heads. A rule of thumb is to avoid rushing the process when figuring out the problematic parts.
