1. Your car is low on oil
It’s common to overlook checking your car’s oil level. Your car relies on a good supply of oil to keep it from stuttering or jerking when accelerating. Be sure to check the light indicator on your dashboard and make sure that it is not one of these colors: red, orange, or yellow.
If your car is low on oil then you will need to go to your local auto parts store and purchase a quart of oil. Be sure to read the label on the oil before you purchase it. The label will tell you the correct specifications for your car. You will want to make sure that the viscosity (the thickness) of the oil is correct as well as its rating. These two things are usually indicated by two numbers such as 10W-30 or 10W-40.
If your car is low on oil then the stuttering and jerking you are experiencing most likely occur when you are coming to a stop. This is because the oil pump in your car (which feeds oil to all of the engine’s bearings) must be at speed for pressure to build up in order for it to work properly. If the pressure does not build up then the bearings will not receive lubrication and will vibrate.
2. problem your spark plugs:
- spark plugs that are too big for your engine
- spark plugs with corroded threads
- spark plugs that are gapped incorrectly
- dirt lodged between the threads of your spark plug
The jerks and stutters you’re feeling might be the result of problems with one or more of the aforementioned factors. To figure out what’s going on, it’s worth turning on your emergency parking brake and checking a few things:
Look at how close your car is to a full stop when accelerating.
If you’re only moving 5-10 feet before you accelerate, your wheels might be getting caught in the seams between the pavement and the asphalt. This can cause your car to vibrate and jerk forward as a result of the friction.
If you’re moving further than 10 feet before accelerating, and you’re still feeling stutters, then it’s possible that your tires are not properly inflated. If they aren’t properly inflated, there may not be enough traction to get your car moving when you step on the gas pedal.
If your tires are properly inflated, and you’re still experiencing jerks and stutters when accelerating, it could be the result of a problem with your spark plugs.
Look around inside your car. Is there anything blocking your view up front, like a bag or something?
If you’re seeing cracks in the windshield or sunroof, it could be causing your car to vibrate in certain spots when you accelerate.
If you’re seeing cracks in your dashboard, it’s probably because there’s a problem with the structure of your car. Look for visible cracks in the body of the car, or any dents, creases or chips that are smaller than 1/4″ in length.
If you’re seeing cracks around your steering wheel and shifter, it could be indicative of a worn steering rack.
Then Start your car and apply the brake pedal. There should be a loud, single-tone chime that sounds when you apply the pedal. If there’s no chime, or if it fades out before hitting your brakes, then you might have a problem with your brake linings and/or your power assist system.
Pull up to 3-5 feet of slack in the parking brake cable (when applicable) and then stop accelerating.
Check to see if you’re leaking fluids. A leaky transmission might not be able to deliver the power from your engine in full, creating jerks and stutters when accelerating.
However; Look around inside your car again.
3. Your fuel injectors are dirty
When the fuel injectors are dirty, they create a problem with the air/fuel ratio and can cause engine hesitation. When the engines hesitate, it causes excessive idle when you try to accelerate. You may also feel that your car jerks or stutters when accelerating. Excessive idling increases carbon deposits in your engine and creates a poor combustion process which prevents good gas mileage.
To clean your fuel injectors, you will need to replace the fuel filter. The most common reason for this problem is a clogged fuel filter. If you are having trouble accelerating or idling on one side of your car, the problem may be with an injector that is leaking and not delivering a proper amount of gasoline. To test to see if there are problems with your injectors, you will need to take it in to a shop which can monitor your engine while it is being tested in cylinders.
Incorrect fuel pressure: If there is too much or too little fuel pressure in the injectors, it can cause uneven combustions and engine hesitation. You will need to adjust the pressure with a “Flex-Fuel Sensor”.
Loose fuel cap: When your gas cap is loose, it will not allow for proper air circulation in the tank. This can cause an excess of air to enter the tank which makes your car take longer to start and causes problems when accelerating.
4. Your air filter and spark plugs are dirty
Your air filter is dirty because enough particulate matter and bacteria is not being removed from the air. There are a few likely causes for this. Either the building has poor ventilation, or people in the building are smoking indoors without considering how their actions affect other people’s health. Cleaning or replacing your air filter can correct this problem.
When you have a dirty air filter, the car is not getting enough fresh air to be able to run properly. If you are running your car in an extremely dirty environment, then this could be the cause of the problem.
As soon as you notice that your car is jerking when accelerating, clean or replace your air filter.
You have to clean or replace the spark plugs after a while. The time that you have to do this depends mostly on the environment that you are operating your car in and on how you drive. For example, if you drive mostly in cities, then it is likely that your spark plugs will last longer than if you drive mostly in rural areas because there is more particulate matter in rural environments and this means that the buildup of dirt on your car will be greater.
5. Your MAF sensor is dirty
Your Mass Air Flow sensor might be dirty, which can make your car jerk or hesitate when accelerating. To find out for sure, blow into the intake and look for an oily residue on the sensor. If it’s there, use a vacuum cleaner or canned air to get rid of the dirt and grime that have been clogging up your engine and causing these issues.
6. Your throttle body is dirty
It’s not uncommon for throttle bodies to get clogged with dirt and debris. The buildup on the throttle body may cause your car to jerk or stutter when accelerating. To fix this, take a clean rag and cover the throttle opening. Turn on your car and use your rag to wipe off any dirt from top of the engine intake manifold, which is located in front of the accelerator pedal.
Sometimes the electric throttle sensor, which is connected to your fuel injection system, will refuse to work if you have a low or dead battery. To fix this stubborn problem, place jumper cables from your car’s battery to your vehicle’s battery. The jumper cables should begin charging the batter within one minute. If this does not work, replace the battery in your car.
There is a malfunction in your electrical system and you need to check all of the relays. If any are loose, tighten them and test your car again. If the problem still exists, you may want to ask for help from an auto mechanic. Depending on what exactly is wrong with your electrical system, the mechanic may be able to fix it for free or for a low cost.
Sometimes one of your spark plug wires will break or become disconnected while you are driving down the road. To fix this problem, place your car in a park and disconnect the spark plug wires. While the ignition is turned off, lift the hood and remove the cover of the headlight. Now, make sure that all of your spark plug wires are connected properly. If there are any missing or loose connections, make sure that you reconnect them correctly before starting up your car again.
7. You have a vacuum leak
One common cause of a jerking or stuttering car is vacuum leaks. You will typically see a drop in your engine’s performance when a leak is present; the engine’s performance will reduce drastically, but if not fixed, it could be very costly in terms of how much gas you use, how much fuel you spend on car repairs and maintenance, and how many people are sick because of your poor performance.
Car leaks usually happen on the side walls near your brakes. They can also happen at other locations like the radiator or oil pan.
Leaks are caused by:
- A valve or hose misaligned or loose
- Defective rubber hoses
- Defective seals between the hose and the engine or rubber hoses
- Bad connections between a hose and a valve. Leaks may also occur from an upside-down flange on your steering column, transmission pan, etc.
so overall; Check your radiator for leaks. A leak from the radiator can affect your engine performance as well as cause the car to run cooler than it should.
8. Your O2 sensor is dirty
A dirty or defective oxygen sensor can cause a car to run poorly, or in severe cases may cause the car not to run at all.
A dirty oxygen sensor is caused by an oily buildup on the sensor, which affects its ability to perform its job properly. The buildup can also prevent your car from starting.
The first step in figuring out why your car is jerking when it accelerates is to try and locate the problem. One of the easiest ways to do this is by checking the oxygen sensor. You can do this yourself within a half hour.
9. Your catalytic converter is clogged
A clogged catalytic converter can cause a noticeable drop in acceleration. This is because the exhaust gas is not at an ideal temperature and pressure when it comes out of the engine, due to the converter being partially blocked.
10. Your engine is misfiring
Your engine runs when you press down your gas pedal, but there is a noticeable delay in your motor accelerating, which results in your car stuttering or jerking forward.
What can cause this?
This is caused by a failure in one or more of your engine cylinders, which means that only every few times your engine combustion meets the demands for combustion, your engine is capable of compressing the air/fuel mixture.
Your air/fuel mixture is therefore not ignited while in the cylinder, which results in only every now and again your engine is capable of compressing the air/fuel mixture.
Another reason is that , Your spark plug could either be faulty or dirty, but more than likely is not and is the cause of your engine misfiring.
11. You have a fuel pressure problem
You recently had to replace, or maybe change, your fuel pump modified for use in water, replace it. It works. So, problem clean up.
The fuel tank has a vent that runs all the way through it, and the cap at the end of the line, where it comes in, has a valve in the bottom which opens at different pressure levels.
When you increase the pressure level in the fuel tank, you have to open up the line to allow more fuel to flow into the pump. This can cause a problem if it is not done correctly.
12. Your transmission is slipping
There are many reasons your car might jerk or stutter when accelerating, but one of the most common causes is a failing transmission. Clutch failure is likely one of the top causes of jerky, hard shifting while driving. There are other causes that could possibly be causing it such as low fluids, low oil pressure, worn components and more.
It is important that your transmission is checked out thoroughly before you replace anything.
Many people are unaware that their transmission is causing the problem, because the symptoms don’t show up during regular driving. The problem usually starts to show itself while accelerating quickly and hard, or when they try to merge into highway traffic.
If there are no warning signs that something is wrong with the transmission when driving normally, it can be difficult to track down what’s causing it.
If your car jerks or stutters while accelerating, it’s time to make an appointment with a car service center and have your vehicle looked at by a mechanic.
In general, car problems tend to be the simplest and cheapest to fix if you can find the issue yourself before taking the car into a shop. With many problems, following this procedure will help you locate them and figure out whether or not it’s a serious issue that needs to be taken care of immediately.
