9 Reasons Your Car Jerks When Accelerating

Last Updated on April 14, 2022

Cars have become increasingly complex over the years, and with that have been a growing number of symptoms that can mean multiple things. Thankfully, many of these symptoms can be diagnosed and remedied without specialty equipment.

If your car jerks when accelerating, it can be an indication of several current or potential problems. Here we’ll go over the most common culprits and how to fix the issue.

Why Your Car Jerks, Lurches, or Stutters When You Accelerate

When car feels like it’s jerking, surging, bucking, or stuttering after you step on the gas pedal, it’s usually a result of inadequate fuel, air, or spark during the combustion process.

However, there are other things that can be the cause. You want to find and fix the problem as soon as possible before it gets worse and costlier to fix.

#1 – Dirty Fuel Injectors

This is a common and annoying problem that can be responsible for a variety of issues. Dirty injectors can cause your car to lose power and make your car jerk while driving at constant speed or from a stop due to frequent engine misfires. You can also hear as the engine stutters from inconsistent fuel intake.

Cleaning the injectors should be done regularly to avoid this problem. Thankfully, this process is quite easy using a fuel injector or fuel system cleaner.

However, the injectors can be so fouled up with carbon deposits that even the best fuel injector cleaner may not do the trick. In those cases, you’ll have to either have to take the injectors out to attempt to manually clean or simply replace them.

#2 – Blocked Catalytic Converter

A catalytic converter is responsible for reducing the amount of pollutants that exit out of a car’s exhaust. When the air/fuel mixture in your engine is too rich, a blockage can develop in the catalytic converter over time which disrupts the airflow of the exhaust system.

This can result in stuttering, jerking, and an overall delay in responsiveness whenever you step on the gas. Besides the jerking, other symptoms may include a rotten egg odor (hydrogen sulphide), a drop in the car’s fuel efficiency, and the check engine light may come on.

You may be able to unclog minor blockages by first using a good catalytic converter cleaner. If that doesn’t work, you’ll need to take it to an auto repair shop to fix the problem which will likely include replacement of the catalytic converter.

#3 – Faulty Mass Airflow Sensor

bad mass airflow sensor

If you notice your car surging forward or jerking at high speeds, it may be due to a mass airflow sensor (MAF) that is failing. Its job is to measure the amount of air entering the engine so it can relay this info to the car’s computer.

The computer then instructs the fuel injectors to provide the right amount of fuel at the right time for proper air/fuel mixture.

With a faulty MAF sensor, you may experience your car unexpectedly jerking or surging forward while driving at higher speeds such as on the highway where it would be most noticeable.

A check engine light should be present when the mass airflow sensor is bad but you can easily confirm via an OBD2 scanner.

#4 – Bad Fuel Pump or Filter

bad fuel pump

The cause of your car jerking while accelerating is often a fuel supply issue. When the correct amount of fuel is not being delivered to the engine, it’s often best to start at the beginning.

In this case it would be the car’s fuel pump. A failing fuel pump would struggle to keep up with fuel demands and cause your car to jerk or surge forward while driving.

Alternatively, you may have a clogged fuel filter that’s restricting the flow of fuel which also can cause issues as fuel delivery is inconsistent. Replacing the fuel filter is a fairly simple and inexpensive process.

#5 – Dirty Air Filter

dirty air filter

As you read this article, you’ll notice an improper air/fuel mixture is often the culprit if your car jerks or sputters when accelerating. Opposite the fuel side of things, is proper air intake.

When not enough air makes it into the combustion chamber, you’ll often get the same issues when not enough fuel.

Your car’s air filter is the first line of defense against dirt and other foreign particles. A dirty air filter will allow some particles to get into the engine, which in turn will affect performance and cause jerking.

Check the condition of your air filter. If it’s dirty, replace it. It should only cost $10-$20 and take a few minutes to replace. Alternatively, you can purchase a reusable air filter such as a K&N which allows for future cleanings instead of replacement.

A clean filter can drastically improve the lifespan of your car’s engine, including reducing or eliminating the acceleration jerks.

#6 – Faulty Spark Plugs

One of the most common causes is also one of the easiest to identify and fix. During the combustion process, a good spark is needed to properly ignite the fuel in each cylinder.

A bad or dirty spark plug can prevent this proper ignition and will cause the engine to misfire. While driving, it feels like your vehicle jerks or shutter when accelerating. 

Fixing this problem is as easy as replacing the bad plug. If you don’t remember the last time you replaced your spark plugs, it may be a good idea to get them all changed out. This is a quick and inexpensive repair. 

#7 – Moisture Buildup

distributor cap

On colder days, condensation can form under the distributor cap. This mainly occurs when you have the car parked outside overnight. This moisture will cause the engine to misfire, thus your car will jerk when accelerating at low speeds.

Luckily, the problem will go away once the water is gone, but repeated moisture buildup can tax your engine over time.

You can avoid this issue altogether by ensuring your car’s parked in a garage or other protected location. A thermal cover can also help reduce the risk of condensation when shelter isn’t an option and you’re expecting colder weather.

#8 – Worn Accelerator Cable

throttle cable

While most cars on the road use drive-by-wire electronic throttle control to accelerate, a physical accelerator cable (or throttle cable) are still found in many vehicles. It acts as a mechanical link between the gas pedal and throttle plate.

Over time, this accelerator cable can wear out. This will cause the car to respond more slowly when you press on the gas and it lurches instead of providing smooth acceleration. You can usually see damage to the cable’s outer coating when examining it, making this problem easy to diagnose.

A damaged cable requires immediate attention, as the car can stop functioning when the cable breaks. Be sure to take it to a trusted mechanic to ensure the replacement is done right.

#9 – Bad Transmission Control Module

transmission control module replacement cost

If you drive an automatic transmission car and notice your car jerking or bucking right around the time your transmission changes gears, you may have a faulty transmission control module (or solenoid).

This part is responsible for gear changes when you accelerate. Gear shifts may be delayed or unpredictable and are often harsh and may feel like the car jerks.

While not a common point of failure, it’s worth considering while you troubleshoot.

  1. Good morning my Juke Techna is loosing power when I accelerate, and thereafter it will jerk and loose power even if its at a low speed and the engine light is on. I. I took it for service, but that was not diagnosed, only the following day when I took it back to complain that the car is now loosing power that I was told its a radiator and thermostat. the care is not overheating though. One of the spak plugs was washed and the rest were not washed or removed. The engine ligh is still on?

    Reply
    • I don’t see how a bad radiator or thermostat would cause the issues you’re describing. I would find a new mechanic and get the car scanned to see what exactly is causing the engine light to come on.

        • I’m not sure I understand. Are you saying the jerking occurs when you hit 3,000 RPM?

          First I’d scan for codes to see if that gives you any indication of the issue right away. If there are no codes, check the transmission fluid. If it feels like the car is slipping or losing power, it could be a transmission issue.

  2. Hi, I have a chevrolet lacetti that that jerks when driving, usually in 2nd or 3rd gear and only when the engine has warmed up. I have changed plugs, maf sensor, leads, coil pack and it’s no different, any ideas to point me in the next direction would be greatly appreciated.

    • Personally I think alot of our issues may have to do with the quality of fuel we are using. I have this issue and did all of the same things to correct it. The only thing that worked, albeit temporarily was a spark plug replacement. I also switched to premium fuel and while I could afford it my redline drove like a champ. It took a little while but when I could no longer afford premium my cars symptoms came back.

      Reply
      • Interesting. Premium is usually just a different octane rating, which means the fuel is more resistant to combustion under pressure. Does your vehicle require premium fuel according to the owner’s manual?

  3. I have a Sharon VR6 although a Passat engine with sensor. The car looses power the more you press the accelerator and it jerk. I consulted so many mechanics and they told me that its from the timing, electrical contact, airflow meter, brain box or pulley for timing. All have been tried and checked but non could solve the problem. Am tired of the car. Please what is the solution? Thanks in anticipation for a positive response!

    • Hello Stephen,

      I also had a VR6 years ago and ran into the same issue. Took it into the shop and the mech told me that 2 of my spark plugs were misfiring. So I paid to have them replace. 2 days later when I picked up my car it drove good around town but when I got on the highway it started doing the same thing. I then took it to a different mech and he told me I was having a misfire from one of my plugs again. Luckily for me the new mech was cool enough to replace the misfiring plug for 10bucks. Long story short in my experience spark plugs can be a reason for misifing in a VR6 even if the first mech didn’t install the new ones right. Luckily for me it was only spark plugs…Hope this help…

    • Good evening! My audi a3 car is just starting to jerk while driving it I don’t know if it’s because around my house it was flooded with water, after the water has dried off, I started the car and a lot of water came from the muffler, the jerking problem has started 3 days after the floodwater came from the muffler. What you may have be thinking the problem is, please?

      Reply
      • Depends how submerged the car was. If it wasn’t running at that time and water just got in the exhaust system, you should be fine after a while.

        The fact that the car is jerking makes me thinking is was being driven through water. In that case, water may have been sucked in from the intake into the engine (check the air filter for dampness). The fact that it starts up is a good thing. First thing I would do is change the engine oil in case water got in there.

        One big thing to note is that water and electronics are a bad combo so there may be some electronics damage including sensors. This will be hard to diagnose and honestly, the hardest to fix.

    • You may have some air trapped in the fuel lines which should work itself out. Alternatively, there’s a chance sediment from the bottom of your fuel tank got sucked up and it may be clogging the fuel filter.

I’ve done a code check on it came back as vvt solenoid so bought it and replaced it… but my problems still not fixed…. like for my issue car runs good but when I press the gas pedal itll go but once at a certain speed like after its warm 20 mph itll act like it’s in neutral but I let off and touch gas pedal itll go but get to say 45mph it does it again…
    Now I thought mayb the valve cover being bad and me having oil and coolant tanks smelling like gas could also cause it to do that but not sure… I’ve thought bout throttle body sensor as well but I know plugs didnt have no oil on them as in they were tanish color when I pulled them… so I’m in a issue and dont know what else could cause that to do that…

    Reply
    • It sounds like there are several issues with the car, so it’s hard to say why there would be gas in the coolant.

      Generally oil in the coolant is a sign of a blown head gasket. You could try performing a leak down test and see if any of the air escapes into the cooling system.

      I don’t think the valve cover gasket has anything to do with the issues you’re experiencing.

        Reply
        • That’s an interesting problem. The jerking and loss of power sounds like maybe not all cylinders are firing. Check for codes and see if you have one that says “Cylinder X Misfire”, where X is a cylinder number. That would be a great place to start.

          When you put new plugs on, make sure you got the firing order correct. Make sure all spark plugs were torqued correctly inside the head. If you pull each of the spark plugs, see if any of them look wet or burnt. This may give you a clue as to what is going on.

          The reason I don’t suspect a transmission issue is because you said the issue is happening while you are standing in a parking lot, if I’m understanding correctly. If that is not the case, let me know.

  32. A co worker of mine had her car jerking, and she wasn’t able to get it over 15 mph, up hills it had trouble with the gas pedal floored.

    My first thoughts were Fuel Filter, and Catalytic Converter.

    So I used my scan tool to get a list of codes.
    I replaced 4 new spark plugs set the appropriate gaps.
    4 new coils, 1 Camshaft position sensor, A new Fuel Pump Assy With fuel filter,
    1 Upstream and 1 downstream or( Bank 1 Sensor 1, Sensor 2) Oxygen sensors.

    The Fuel Injectors had been replaced in the fall of 2021, So I pulled those and cleaned them thoroughly. Air Filter is clean.

    No rotten Egg smells, Overheating, or low exhaust pressure and No Code PO420

    The car is still doing the same exact thing. 10-15 mph, Rough Idling there are no scan tool codes that havent had the parts replaced.

    What would you recommend doing next?

    This is a 2013 Hyundai Accent GLS 1.6 (July Manufacture Date Code) it has about 145,000 miles on the odometer.

    • Use a scan tool that gives you live data and check some of the engine parameters. For instance, look at fuel trims and air fuel ratio to see if you’re running excessively rich or excessively lean. If there are any remaining codes, please post them here.

    • Could be some sediment or debris at the bottom of the tank that the fuel pump sucked up, which is now causing issues. Could be bad fuel. Perhaps changing the fuel filter will help. Hard to say without doing some more digging into the problem.

  35. Jerking or Bucking when accelerating of any Nissan is most often cause by a silent failure of the Crankshaft Position Sensor. OBD scans often do not detect the failure which is only a partial failure of the component in addition to the lack of the appearance of a check engine light.

    This problem can only be rectified by using the appropriate DENSO (OEM Supplier) Sensor for the vehicle.

    This is so because the ohms or resistance, the voltage and the signal from the sensor all have to be at the correct Nissan Specifications to be recognized and accepted by the Nissan Engine Control Modules.

    I’ve tested over 9 aftermarket brands for replacement CKP sensors from accessible online and regular auto parts stores and found the DENSO Sensors to be the only ones to work properly on NISSANS. The correct sensors can be recognized with the imprints similar to ” A29-662 L41 SGI B002 1707A4″. That imprint is the correct sensor any Nissan with a VQ35DE Engine.

    Reply
    • I don’t know. This will probably require a mechanic to look at the car and give you an accurate diagnosis. The idle air control valve was my first thought for the issues when the car is not in motion, but the idle air control valve shouldn’t affect the car while it’s moving. Could be an issue with one of the accessory pulleys or belts too I suppose, or maybe even something inside the engine.
