You’ve probably experienced this problem before: your car jerks or lurches when you brake or accelerate. The cause is a complex mystery, but there are several possible solutions. Read on to learn the causes, symptoms, and repairs for this problem. You’ll be glad you took action right away. Regardless of whether the jerks occur on an ordinary road trip or when you’re in a sudden situation, they’re a sign of a more serious problem.


A jerking car during slow driving may be caused by a number of issues. A faulty MAF sensor, a bad ignition coil, or a bad transmission system are some of the most common causes. The MAF sensor measures the amount of air entering the engine and feeds the data to the engine control unit, which determines how much fuel to burn in order to provide the maximum amount of power. Some MAF sensors are fitted with an internal heating element, which helps warm up the sensor to the appropriate temperature.

Another problem that causes a car to jerk while driving is a bad catalytic converter. If your catalytic converter is clogged, it can cause your car to lose speed rapidly. In addition, a bad catalytic converter can cause the check engine light to come on. To fix the problem, you can apply a catalytic converter cleaner and unclog minor blockages. Otherwise, you can take your vehicle to an auto repair shop for a new one.

Another possible cause of the jerking motion is dirty fuel injectors. The injectors are responsible for spraying the right amount of fuel into the engine, so when they become dirty, they lose power and misfire. If this is the case, cleaning or replacing the injectors will fix the jerking problem. If you’re unsure, you can try a Jerry app to compare car insurance rates.

If the problem is not an engine, a failing throttle body may be the culprit. This malfunctioning part is a common culprit for car jerking when slowing down. Regardless of the cause, a faulty throttle body should be repaired immediately to avoid severe engine damage. If left unchecked, this problem can lead to misfires and other problems as well. To ensure that you don’t have to suffer through this annoying problem, check your vehicle’s ignition and fuel systems and replace them as necessary.

Other causes of jerking car motion include a leaking transmission, a faulty torque converter, a faulty turbo, or a faulty engine mount. It’s important to seek immediate car repair when the jerking is unrelenting. If you can hear a whistling or grinding sound while driving, check for a leaking transmission. It’s important to repair the transmission if the fluid level is low.


When you’re trying to slow down your car, you’ll likely notice that it jerks when you’re slowing down. This jerking motion can be caused by several things, including an imbalance in the fuel and air system. Check the parts of your car that are causing this problem and make any necessary adjustments. Also, remember that jerky motions can occur even at constant speeds.

One of the most common causes of car jerking when slowing down is a faulty MAF sensor. These devices measure how much air is entering the engine and send that data to the engine control unit. The control unit then calculates how much fuel is needed for optimal combustion. Some MAF sensors are equipped with an internal heating element. If yours doesn’t, you should take it in for a tune-up.

Another possible cause of a jerking vehicle is a dirty fuel filter. A dirty filter will clog up the fuel system and cause the car to jerk. A dirty fuel filter may be blocking the fuel lines, which will cause the car to struggle to accelerate. If you’ve changed your fuel filter recently, you’ll likely notice a difference. If it’s still jerking, you should contact your local dealership.

Other possible causes of car jerking when slowing down include transmission or catalytic converter issues. Catalytic converters can be worn out or fail prematurely. However, the problem may be something else entirely. The transmission may be leaking, and you can see it under the car. Getting a mechanic out to check it is usually the best solution. If you’ve been having the problem for quite a while, a simple replacement could fix it.

Another cause of car jerking when slowing down is a leak in the throttle body. The throttle body is responsible for controlling air intake in the engine. If it’s damaged or leaking, it won’t properly control the fuel supply. This can lead to a misfire and other problems. If it’s a faulty throttle body, you should visit your mechanic as soon as possible.


Many drivers experience car jerking while slowing down. There are many potential causes. Common faulty parts include the transmission, faulty torque converter, and leaking engine mounts. The turbo may also be malfunctioning, causing the car to jerk when slowing down. If you’ve noticed the problem, make an appointment to have your vehicle serviced by a mechanic. A mechanic can determine the exact cause and repair it as soon as possible.

The problem can also be caused by improper gear manipulation, such as changing gears at too high a speed. An expert mechanic will be able to determine which components are at fault. Another possible cause is a defective torque converter, which regulates the rate at which the engine and transmission work. If the car is not in manual transmission, the problem could be with the torque converter. If this is the case, the problem is more likely caused by a faulty torque converter.

The check engine light will also indicate if there’s a problem with the vehicle’s engine. It’s best to get the issue fixed quickly, as any delay could result in major engine damage. The following are some common causes for car jerking when slowing down:

A jerky car can be dangerous to drive. It can be difficult to gain and maintain speed and can cause a car to slam into another car. Ultimately, this problem can be fixed by a mechanic, but the sooner it’s diagnosed, the better. If you experience this problem, take it to a mechanic immediately. It’s not worth risking your safety.

Another cause of car jerking is a failed throttle body. This component regulates air and fuel intake to the engine. If the throttle body is faulty, this can cause the engine to over-react and lose power when slowing down. Even a failing ignition coil can cause the car to jerk when slowing down. In such cases, you should replace the ignition coil.


If your car jerks when slowing down, you may be experiencing a faulty throttle body. This is a common problem, but you should consider getting your car checked out by a mechanic. Not only will they be able to diagnose the problem for you, but they will also be able to provide a quick fix. If you’re unsure about the symptoms, read on to discover what to look for.

A broken throttle cable is another likely culprit. It is a mechanical link between the gas pedal and the throttle plate. If the cable becomes worn or brittle, your car will struggle to accelerate and may jerk while slowing down. You should also inspect the coating of the throttle cable if you notice a jerk in your car. If you’re unsure, consult a mechanic immediately.

If the problem persists, you may want to consider checking the heating element sensor. If the sensor is clogged or dirty, it can send bad information to the engine computer. Another cause of a jerk is a malfunctioning ignition coil. When the ignition coil fails to provide a good spark, the air/fuel mixture in the engine cannot properly burn. If this part is causing the jerk, you should replace it to prevent future misfires.

A jerk when slowing down can also be caused by a malfunctioning brake system. The brakes may need bleeding. You may also need to replace your brake pads. Worn rotors may also be the cause of the problem. You may have to replace or resurface them. If you’re experiencing a jerk when slowing down, you should take your car to a mechanic to make sure the brakes are working properly.

If you suspect a fuel supply issue, your next step should be to check the fuel pump. In many cases, the problem is a faulty fuel pump. Alternatively, a dirty fuel filter can cause the car to jerk when accelerating. Changing the fuel filter is a simple and cheap solution. A fuel pump can also cause a jerk when slowing down, so check your car’s fuel supply first.
