13 Reasons And Solutions For Car Jerks When Accelerating

When a car starts jerking as you accelerate it, there is undoubted that it’s usually a sign of an impending issue. However, sometimes car jerks when accelerating is a common problem faced by several car owners. But don’t worry because this symptom also has a solution like other car problems.

Car Jerks When Accelerating – Reasons & Solutions

You must be aware of all the feasible reasons behind the problem in accelerating before jumping to the solution. The car jerking problem happens to be an issue common in both manual and automatic cars.

1. Polluted air filter

What does it mean when your car jerks? Air filters keep the car away from the road pollutants such as dirt, debris, and other things that contaminate the engine. Over time, filters are susceptible to accumulating obstructions and build-ups. In addition to pollutants, dirty air filters are also the cause of inefficient fuel combustion.

Therefore, you should wipe those off and then check to make sure the symptom will not happen again. For example, Toyota Camry is said that sometimes jerk when accelerating and the most common reason behind is air filter pollution. Furthermore, some people think that Toyota Camry is a bit sluggish when accelerating from a lower speed, so notice to accelerate from a standstill.

2. Damaged fuel pipes

The primary job of fuel pipes is transferring fuel from one section of the engine to another. It is possible that a car jerks when accelerating due to broken fuel pipes. In fact, the situation may even get worse and cause a fire in the car. Usually, it gets difficult for the car to accelerate due to disruption in fuel transfer. The internal combustion is susceptible to other major issues, once a fuel pipe leaks.

To deal with this problem, check for leaks that may be chewed off by rats. Moreover, owners of old cars should pay attention to this issue because they are likely to have a faulty flue line.

3. Damaged carburetor

The carburetor blends and regulates the right amount of fuel and air as it goes into the engine cylinders for appropriate fuel combustion. A damaged carburetor is responsible for the poor performance of the car as well.

Like a dirty air filter, an improper carburetor also causes a car to jerk as it disturbs the fuel-air mixture balance. If you figure out an issue with the carburetor, check the fuel inlet, throttle lever, idle jet, or throttle valve.

4. Accumulated moisture in the distributor cap

The weather is also one of the major reasons why a car jerks when accelerating. Obviously, it usually occurs during the winter with very low temperatures when you park your car outside. Moisture gathering in your car’s distributor cap can cause the car to jerk and lead your engine to misfire while you accelerate.

The solution here is quite simple: prevent parking cars in a cold and wet place and try to find a warmer spot instead.

5. Polluted injection system, fuel tank, and filter

Gunk or dirt can cause severe problems to your car. A polluted fuel tank, filter, or injection system can cause a car to jerk very easily. It disturbs the flow and supply of the fuel into the engine. Furthermore, insufficient fuel in the car causes it to jerk as you accelerate the car.

Nevertheless, it isn’t too hard to fix and you don’t need to hire someone to do it. You can buy a special kit solely for injectors in the local hardware store or online and clean that area carefully. It is also advised that you should do it regularly to make sure your engine doesn’t get clogged up with dust and dirt.

6. Poor engine tuning or blockage in the engine

If everything comes clean, you must check your engine. Basically, engine tuning involves nothing more than adjusting a vehicle’s engine as well as the fuel system. Effective engine tuning boosts your car’s performance and eliminates the car’s jerking.

Besides poor engine tuning, one of the most frequent reasons for a car jerking when you accelerate is a blockage in the engine. Jerking happens as gasses are not coming out of it when they are supposed to. In addition, you should not ignore the “Check Engine” light” in your car, especially when it is blinking. This problem occasionally happens in Honda Accord and Nissan Murano. In this case, sending the car to a professional mechanic to get it tuned or remove the blockage is the best solution.

12. Drained acceleration cable

A car jerking may be a result of a very worn-out acceleration cable. You will notice some signals for this symptom such as your car taking excessive time to respond when you press the accelerator and start jerking. Another symptom is that if you take a look inside, the outer covering of the acceleration cable will be damaged.
The best you can do is to change the drained acceleration cable as soon as possible, as the car will jerk and stop at any moment if you leave it to break. Take the vehicle to a mechanic to solve the problem.

13. Motor winding

Engine winding can be another reason for car jerking. Wear of the engine’s winding is most likely to be caused by the heavily stressed engine – for example through hard acceleration. Signs for this are:

• If there are more than one winding and one of them is broken, the car will jerk.
• If there’s only one winding, the car will not start.

The use of an Ohmmeter is the only way to know this, so if you don’t have one, you should check with a mechanic to know if the motor winding is the reason your car is jerking.

Summing Up

These are reasons and solutions for car jerking while accelerating. So, keep trying to keep all parts of the engine clean and oil them regularly. This is one of the important maintenance tips you must know as a car owner. Also, your car jerks when accelerating due to engine problems, so the right gasoline usage for your car’s engine is for better functioning.
