When Accelerating At Low Speeds, Why Does A Car Jerk?

When your automobile jerks when accelerating at low speeds, it might irritate you from the moment you get inside it. Even something as basic as backing out of your driveway slowly can cause your car to jerk, making you question whether you should be driving it at all.

When an automobile jerks when accelerating at low speeds, it’s almost often due to an issue with the spark plugs in it. A quick tune-up should be enough to put an end to the jerking for good. However, there may be an issue with the air intake system or the catalytic converter. When an automobile jerks when accelerating at low speeds, these are some of the most typical causes.

On The Distributor Cap, Moisture

If it’s snowing outside, moisture gathering on the distributor cap may cause jerky acceleration. This usually happens when you park you’re automobile outside in the winter. You can avoid this by parking your car in a warmer location.

Carburetors That Aren’t Working Properly

The carburetor is in charge of regulating the amount of gasoline and air combined together before entering the engine. Carburetor failure causes your car to lurch when you accelerate, as well as perform poorly overall.

Acceleration Cables That Have Been Damaged

It’s possible that the acceleration cable has been damaged. This cable connects your gas cable to the throttle plate on your engine. The cable pulls the throttle open when you press the gas pedal, allowing your car to accelerate.

Gas Lines That Have Been Damaged

Gas lines carry gas throughout your engine. A problem with a gas line, on the other hand, can result in a loss of pressure in your car, causing it to jolt forward. A faulty gasoline line could even cause your motor to catch fire in extreme situations. Make sure the fuel line doesn’t have any holes in it.

Catalytic Converters Blocked

It’s possible that your catalytic converter is clogged. A blockage might occur if the air-fuel mixture travelling through your catalytic converter becomes too rich. When the driver hits the gas pedal, the car often jerks. With a decent catalytic converter cleaner, you might be able to clear it out. Otherwise, you’ll require the assistance of a mechanic.

Cylinders That Have Been Damaged

Your engine’s ability to perform properly will be harmed if the cylinders are damaged, resulting in an engine misfire. You should contact a professional about this problem so the cylinders can be serviced or replaced. Otherwise, your engine would quickly deteriorate.

Filters That Is Dirty

Filtering impurities out of your engine is the job of the air filtering system. However, these pollutants might accumulate over time, causing your car to not accelerate effectively. You can simply remove the air filters and wipe them clean before reinstalling them, or you can replace them entirely.

Spark Plugs That Have Been Worn Out

It’s possible that your spark plugs have worn out and are unable to ignite the fuel in the piston quickly enough. As a result, your car may not accelerate as rapidly. Spark plugs, fortunately, are inexpensive to repair and replace.


It’s possible that there’s a blockage stopping your car from receiving the fuel it requires to accelerate. Air and fuel combine to form a spray that powers your engine. If something gets in the way, your car may struggle to accelerate.

Fuel Injectors That Have Been Ruined

Fuel injectors that are dirty are one of the most common causes of jerky acceleration. When you try to accelerate from a stop or drive at a regular speed, your car loses power due to a filthy injector. A misfire in the engine caused this.


It’s all about What Causes A Car To Jerk When Slowing Down? If your automobile twitches when accelerating, depending on what your mechanic says about it, you might want to consider selling it. If the vehicle is older, it may not be worth the money to replace the catalytic converter or do any of the other costly repairs that may be required.

You’d be better off selling your automobile for cash and letting someone else handle it for a change. When your car isn’t working properly, you’ll want to take it to an automotive service facility that can diagnose the problem so you don’t have to pull it off the road.

Frequently Asked Questions

When I slow down, why does my automobile jerk?

This could indicate a clogged or failed mass air flow sensor. The mass air flow sensor is an intake system component that monitors air intake as it is combined with fuel before being injected into the engine.

When a car jerks, what causes it to do so?

In fact, the most common reason of a jerking vehicle is a clogged fuel filter. A faulty gasoline filter will also cause the car to cut out or lose power when driving up an incline, in addition to jerking. This happens because fuel demand rises when the engine is working hard, and the blocked filter limits the required flow.

Is it possible for the transmission to cause the car to jerk?

Automatic transmissions that jerk, shake, or shift hard during a shift change may indicate that the transmission fluid needs to be replaced or that the fluid level is low. Abnormal gear changes in manual transmission automobiles could indicate faulty gear synchro, worn clutches, or other, more serious concerns.

At 40 mph, why does my automobile jerk?

When trying to shift gears, a faulty transmission may frequently kick forcefully. The engine’s RPMs will increase when the automobile reaches 40 mph. A defective transmission at that point might cause the automobile to jerk, possibly accompanied by loud slamming sounds.
