Have you noticed your car jerking while accelerating? If yes, you must get to the bottom of it as soon as possible! As a driver, don’t you hate it when the car jerks out of nowhere and risks spiralling out of control? From spilling coffee on yourself or the seats, to bumping your head on the steering wheel, there are many unpleasant effects of car jerks.
It is not just about comfort or convenience; addressing car jerks is important due to safety reasons. An aggressive car jerk could cause you to lose control and break lane discipline. This can prove fatal on highways or in heavy-traffic areas.
If you are wondering what could be the reason behind the car jerks, you are in the right place. At Mark Jackson Automotive, we have over 48 years of experience repairing and servicing cars in Southport and the Gold Coast, QLD. In this blog, we list the top 4 reasons your car jerks during acceleration.
Fuel injectors ensure a car’s smooth operation. It is the fuel injectors’ job to ‘inject’ or deliver the right amount of fuel into the car’s combustion system. However, due to its proximity to the combustion system, it is prone to impurity accumulation.
When this accumulation is left unchecked, the fuel injectors clog and fail to deliver fuel consistently to the combustion system. If you notice your car jerking while accelerating, it could be due to the sudden ‘dumping’ of fuel, or the lack of it thereafter.
You must get the fuel injectors checked by a certified mechanic to prevent clogging, which causes the car to jerk during acceleration.
Air filters are the first line of defence against dirt and contaminants trying to enter the car’s combustion system. Imagine what would happen if the filters themselves are dirty! You must clean or replace dirty air filters on time to ensure only clean air is drawn in when you accelerate. If not, there is a risk of the car jerking when accelerating at low speed.
Simply put, a car needs both clean air and fuel to ensure optimal performance. A clogged or dirty air filter means sporadic mixing of air and fuel. This causes sudden jerks and compromises the car’s performance. A clean air filter ensures consistent mixing of air and fuel, preventing sudden jerks.

Spark plugs are among the most important components of your car. What do they do exactly? As the name suggests, they are responsible for creating a spark that ignites the fuel-air mixture within the combustion system.
They keep the car running by firing high-voltage electricity hundreds of times per second. Now, even the best spark plugs don’t last forever. Due to regular wear and tear, they gradually lose their consistency and efficiency. As a result, you experience car jerking while accelerating.
Identifying and replacing worn-out spark plugs is the simplest and efficient way of dealing with this problem. It is also very affordable, so you don’t have to worry about burning a hole in your pocket. Difficulty in starting the car or the ‘Check Engine’ light turning on are other signs of damaged spark plugs.
Acceleration cables are specialised cables that are a crucial aspect of your car’s accelerator system. It seamlessly connects the accelerator pedals to the throttle body or the carburettor (if present).
A well-maintained or brand-new acceleration cables ensure smooth and steady acceleration. With time, due to overuse or normal wear and tear, acceleration cables are damaged. This compromises their efficiency, causing sudden car jerks while accelerating due to uneven throttle response.
Timely intervention in the form of inspection, maintenance, and replacement offers an effective solution to this problem.
