Why Is Your Car Stuttering When You Accelerate?

There are many reasons why you may feel some stuttering when you hit the gas. They range from simple fixes to some significant issues you’ll need to call a professional for.  Let’s go over some of the possibilities and walk you through diagnosing and fixing some of them.

Fuel Components

The fuel makes the car run, along with the air, and it passes through a variety of components that can have issues or get clogged:


The fuel pump serves the fuel towards the engine, but if it’s not working correctly, it won’t distribute it enough, if at all. You’ll need a hand with this issue.


When the fuel filter gets dirty, the clog restricts the fuel from getting to the engine. Filter changes are an easy and affordable fix you can handle.


The fuel injector controls the flow from the pump into the engine cylinders and will also cause jerking when accelerating if it’s clogged. The engines need fuel. On the bright side, unclogging it is something you could do yourself with a little patience and research by running cleaning fluid through an empty tank.

Pipes & Line

The fuel pipes and line can be insufficient and can cause hazardous fires, so please seek advice from a professional.

Stick Shift

It’s inevitable that while learning to drive with a stick shift, there will be some jerking while transitioning gears. This is totally normal, and you will get better with practice.

Air Filter

The last thing you want is debris in your engine. When the air filter looks clogged, it’s time for a change, which is luckily cheap and easy to do.

Catalytic Converter

When the catalytic converter is blocked, you can tell. If you experience a stutter while smelling sulfur and notice tinted smoke pluming out of the exhaust, it’s likely the catalytic converter. The catalytic converter helps manage the gas emissions from your car, so they don’t back up internally. If this is the case, get a hold of a mechanic like FTS Auto .

Distributor Cap

When this gets moist from outside conditions, it can prevent the coil’s electric spark from properly igniting. The cars that use this ignition system will need to dry out a bit.

Accelerator Cable

This cable can get worn over time, causing a disconnect between the gas cable and the engine throttle plate. When they break or aren’t taut, they aren’t able to pull the plate in order to release the fuel on command.

Spark Plug

The spark plugs are the catalyst to power. Without them, the car isn’t going to get far. They light the fuel and air to create combustion surrounding the engine in order to fire up the mighty pistons. This system needs them, and their cables, to be functioning, otherwise you will experience jerking, loud engine sounds, or a failure to start.


The cylinders hold the combustion that powers the vehicle. When they’re damaged, they will dilute the process, causing misfires.
