A malfunctioning mass airflow sensor prevents the proper amount of fuel from being delivered from the fuel injectors by measuring how much air is entering the engine and relaying this information to the vehicle’s computer. Usually, a failing mass airflow sensor will provide an error code that illuminates the Check Engine light. While traveling at a high speed, this warning could be followed by an unexpected jerking or rushing sensation. A failed mass airflow sensor may cause a car to stall out right away.
Engine Vacuum Leak: To ensure an adequate fuel/air mixture, your engine’s computer uses vacuum lines to assist in calculating the necessary position of the fuel injectors. The engine may operate poorly as a result of a vacuum leak, and the computer may also provide an error code. A car with a vacuum leak could jolt when moving quickly and have trouble starting.
Failure of the fuel pump: The fuel pump in a car is in charge of transferring gasoline from the fuel tank to the engine, where it can be combined with oxygen to power the engine. When a fuel pump starts to malfunction, it could find it difficult to regularly supply the right amount of fuel to the engine. A jerking or rushing sensation could be caused by the fuel pump failing suddenly and substantially increasing pressure. Additionally, if you’re hauling something or driving uphill, your car can suffer.

To function, your Sonata requires fuel (obviously). A jerking sensation may be brought on by one of your fuel injectors that is clogged or not firing properly.
A defective fuel pump or fuel filter might also result in a jerk when accelerating, in addition to bad fuel injectors. There is insufficient fuel pressure at the fuel rails when either of these malfunction.
If the air intake is blocked by something foreign, you should inspect it. Or, if your air filter is extremely unclean. The Sonata will jolt and the air fuel ratio will be off if there is not enough air.

It seems like there is a problem with the engine’s electronics, causing the engine to run very rough or not fire at all. There is a need to solve this because it won’t “go away.” Visit a more competent mechanic.
The 2002 Hyundai Elantra that we are attempting to repair has similar issues. The only thing I can say is that the battery of the automobile won’t keep a charge. Although the battery and alternator have been changed, the issue persists. The voltage regulator or perhaps the computer should next be examined. The other issue we’ve noticed is that after a jump, the car seems to run fine while the jumper cables are still attached, but as soon as we remove the cables and the car starts to warm up, the engine starts to misfire so badly that it appears as though it might jump out from under the hood. The car then refuses to start on its own, and the misfiring continues until it stops running.
My 2015 Hyundai Sonata has been jerking a lot for a while. When my transmission temperature is high, my car may occasionally signal to me while I’m in traffic to stop accelerating. Prior to being able to move the automobile again, I have to wait for a while, perhaps for 30 minutes. I’m curious as to what this incident’s potential causes might be.
fuel filter clog
Your Hyundai Sonata’s fuel filter may be clogged, which prevents the engine from receiving adequate fuel. As a result, the vehicle loses power and jerks when accelerating. The worst-case scenario involves an engine cutout while you’re driving from a lack of fuel.
If this occurs, the Sonata’s control unit can identify the fuel issue and the engine check light will come on. When you attach an OBD2 scanner to your car, you can receive the error number P0087, which denotes a problem with the fuel delivery system.

Hey guys! My wife and I recently purchased a 2012 Sonata hybrid, and it has about 7,000 miles on it at this point. My wife and I have both experienced the car bucking or jerking as we pull out over the past month or so. Additionally, when ascending a hill, it occasionally feels as though the engine hangs while switching from the electric to the gas engine. The gas engine will rev but not pull, so I have to take off the gas to get it to engage and continue ascending the hill. Oh, and when it does this, the car is at operational temperature, not frigid. The auto is perpetually in blue mode. We filled it with high-quality gas. Why in the world is it flawed? When I take it to the dealer to have it checked, I fear they will tell me there is nothing wrong because there aren’t any lights flashing to indicate there is something wrong. Has anyone among you encountered issues with this jerking/bucking nonsense? It only does it occasionally, of course.
Why does it seem like my car is jerking?
When you press the gas pedal, your automobile may feel like it is jerking, surging, bucking, or stuttering. This is usually because there is not enough fuel, air, or spark to complete the combustion process.
There are other factors, though, that could be the reason. Before the issue worsens and becomes more expensive to resolve, you want to identify and address it as quickly as you can.
The automobile jerks when I slow down; why is that?
Your automobile makes a sound as it jerks, but the sensation is more noticeable. Usually, you experience quick tremors. It resembles your car gasping for breath.
Most frequently, an imbalance between the air and fuel coming to the engine is what causes a car to jolt while slowing down. It is crucial to troubleshoot because there are numerous parts and components that could be the source of this imbalance.
Your automobile may potentially jolt due to an issue with your brakes or tires. It’s possible that your gasoline filter is clogged.
Impurities are kept out of your engine by the filter, but when it is unclean, it is unable to do so. They eventually end up in your engine, where they could cause an abrupt jerk.
The mass airflow sensor checks if the amount of fuel and air entering the engine is balanced. If the sensor malfunctions, the two become unbalanced and your automobile may either receive too much or too little fuel.
Additionally, this can cause your car to jerk. Your automobile can jerk if your throttle position sensor is malfunctioning. The sensor controls the throttle position, and if it malfunctions, your automobile may jerk.
Last but not least, a faulty or broken tire might make your car jerk and pull.
Simple objects like metal, glass, or nails can harm your tire sufficiently to cause alignment issues.
What causes an automobile to lurch when accelerating?
Fuel injector clogging is a relatively frequent problem that can lead to a variety of auto issues. Your automobile may jerk if a clogged fuel injector prevents it from getting the fuel it needs to accelerate. The injectors may not be supplying enough gasoline if you hear the engine of your car stuttering.
You should routinely clean the injectors to resolve this. The issue of the automobile jerking could be resolved by using a fuel injector cleaning solution. Injectors may need to be removed, cleaned, or replaced by a mechanic if the obstruction is too bad.
Why does my car jerk at random while I’m driving?
Expired Spark Plugs The reason your automobile jerks while accelerating is because your spark plugs are not quickly igniting the fuel in every piston cylinder. Spark plug replacement is the only appropriate course of action if they are worn out because it is typically a quick and inexpensive fix.
Why is my car shaking and my engine light on?
My car started shaking while I was driving home from work, and the check engine light illuminated. It came out of the blue, which really shook me out, but I was able to get home without incident. Why did the engine light come on and now my car is jerking?
In less than two minutes, find out if your auto insurance is being overcharged.
Glad to hear you made it home safely after what seems like a terrifying ordeal! Your check engine light turning on and your car jerking are two indicators that can point to a variety of various issues with your automobile, so you should take it to a repair as soon as you can to figure out what’s wrong.
Among other things, some of those issues may be caused by unclean air filters, clogged fuel injectors, broken engine cylinders, worn-out spark plugs, fuel system obstructions, malfunctioning sensors, damaged acceleration cables, or worn-out spark plugs. You don’t want to risk further harm to your vehicle, so having it looked at isn’t something you want to put off. Depending on the problem, it can be a simple remedy or one that requires major repair.
It’s a good idea to confirm that your current auto insurance policy still fits you and your vehicle while your automobile is being examined. You may quickly and simply compare comparable quotes from leading auto insurance carriers in one location with the Jerry app.
Starting up takes less than a minute, and the typical Jerry user saves $887 year!
When I hit the gas pedal, why does my automobile jerk?
This component plays a crucial role in decreasing the pollutants that are released from the exhaust system. When the air/fuel ratio in the engine is too rich, the exhaust might be disrupted, which can make the automobile jolt or react when you press the gas pedal. A malfunctioning catalytic converter may also emit unpleasant odors and reduce fuel efficiency.
Can a car jerk because of the transmission?
You might find it difficult to shift gears or the transfer may feel jarring if your car has trouble accelerating. There may be a jerk, clang, or thud sensation. This is frequently brought on by issues with the transmission fluid, vacuum, or a malfunctioning sensor.
Older automobiles use the vacuum modulator valve to help them choose when to change gears. The valve and the intake are linked together by a hose. A blocked, cracked, damaged, or bent hose prevents the transmission from receiving the signal.
Problems can arise with transmission fluid as well, whether it is polluted or has a low fluid level. If it is foggy and dark, it has to be changed. It should be clear and bright red.
Sensors are used by modern automobiles to control a variety of operations, including gear shifting. If your automobile is modern and the vacuum and fluid are working properly, the issue may be a malfunctioning sensor. To fix this, you’ll need assistance from experts.
Is it okay to operate a jerky vehicle?
High-speed surges or jerks can be dangerous, especially in congested areas or inclement weather. Stop driving if your car shakes when going fast, and have a mechanic look it over. Being vigilant and having a mechanic check out a car with a warning light can help limit potential damage and prevent more expensive repairs because many of the problems that might produce this jerking sensation also set off a warning light.
