Reasons Why Your Car Is Stuttering When Accelerating

Reasons Why Your Car Is Stuttering When Accelerating

When you step on the gas, there are a variety of reasons why you might stutter. They range from simple fixes to more serious issues that require the assistance of a professional. Let’s go over some of the options and show you how to diagnose and fix some of them.

The Path of the Fuel Components

The fuel, along with the air, makes the car run. The fuel passes through a number of components that can malfunction or become clogged:

  • Pump. The fuel pump delivers fuel to the engine, but if it malfunctions, it will not distribute it properly, if at all. You will need professional help to fix this problem as soon as possible. 
  • Filter. When the fuel filter becomes clogged, it prevents fuel from reaching the engine. Filter replacements are a simple and inexpensive fix.
  • Injector. If the fuel injector becomes clogged, it controls the flow of fuel from the pump into the engine cylinders and causes jerking when accelerating. Fuel is required for the engines. On the bright side, by running cleaning fluid through an empty tank, you can unclog it yourself with a little patience and research.
  • Pipes and Line. Fuel pipes and lines may be insufficient, resulting in dangerous fires. That is why you need to seek professional advice.

Other Potential Factors

Reasons Why Your Car Is Stuttering When AcceleratingOutside of the fuel components, there are other reasons why your vehicle may be stuttering: 

  • Stick Shift. When learning to drive with a stick shift, there will inevitably be some jerking when changing gears. This is completely normal, and with practice, you will improve.
  • Air Filter. Debris in your engine is the last thing you want. When the air filter appears to be clogged, it is time to replace it. Fortunately, this is inexpensive and simple to do.
  • Catalytic Converter. You can tell when the catalytic converter is blocked. It’s most likely the catalytic converter if you get a stutter while smelling sulfur and see tinted smoke coming out of the exhaust.
  • Distributor Cap. When this gets wet from the elements, it can prevent the electric spark in the coil from properly igniting. Cars with this ignition system will need to be dried out a little.
  • Accelerator Cable. The gas cable and the engine throttle plate can become disconnected over time as this cable wears out. They cannot pull the plate in order to release the fuel on command if they break or are not taut.
  • Spark Plug. The catalyst for power is the spark plug. The car won’t get very far without them. To fire up the mighty pistons, they light the fuel and air to create combustion around the engine.
  • Cylinders. The combustion that propels the vehicle is contained in the cylinders. When they’re damaged, the process becomes diluted, resulting in misfires.
