Are you tired of finding solutions for why my car jerk when I accelerate? All kidding aside, jerking is a real problem that some drivers face. And frankly, it can be quite scary in certain situations. It’s very unsettling to feel your car jerk as you accelerate. Not knowing exactly where your vehicle is going to go or if it’s even going to stay on the road is not the feeling you want when you’re behind the wheel.
Furthermore, when your vehicle jerks when you accelerate, it’s definitely a sign that something is wrong. So, no matter the reason, you shouldn’t ignore it
If your vehicle begins to jerk, then it’s time to visit a Downey auto mechanic to get it fixed. So why do vehicles jerk? Here are some common reasons:
Top Reasons for Car Jerking During Acceleration
Catalytic Converters Are Blocked
Over time, catalytic converters get old and break down. A common problem is for them to form blockages. When that happens, they either need to be cleaned or replaced. Either way, once the clog is removed, your acceleration should return to normal.

Fuel Injectors Are Dirty
Fuel injectors get dirty as gas passes through the fuel lines. Over time, the buildup can affect how well the injector functions, which can affect acceleration. Fuel flow can be slowed, and that can cause the jerking feeling.
Spark Plugs Are Worn Out
Like most other parts, as your spark plugs get old, they wear out and have to be replaced. Replacing spark plugs ensures your vehicle doesn’t suffer any power shortages. When they get old and power is compromised, it can cause your vehicle to jerk when you accelerate.
Air Filters Are Dirty
If your air filters get clogged and/or dirty, it can also cause your vehicle to stutter, which can feel like jerking. If your air filter is dirty or old, then simply replace it, and you should feel some improvement.
Damaged Acceleration Cables
Your vehicle has specific acceleration cables that help it accelerate. If these cables get damaged or wear out, your vehicle will have a harder time accelerating, and that leads to jerking.
Gas Lines Are Damaged
It’s not super common, but sometimes a gas line can get damaged. If that happens, it can impede fuel from flowing through the vehicle properly. That can affect how well your vehicle functions. If your gas lines get damaged, they need to be repaired or replaced for your car to work properly.
Cylinders Are Damaged
Another possible cause of jerking is damaged cylinders. If your cylinders aren’t working correctly, it can lead to jerking. To fix this issue, it’s usually best to just replace the old cylinders.
Carburetor is Defective
Carburetors supply air and fuel to your vehicle’s engine. If the carburetor doesn’t work right or quits working altogether, your engine won’t function properly, which reduces acceleration. You will have to either repair or replace your carburetor to stop the jerking.
Bad Fuel Pump or Filter
Problems with the fuel supply frequently cause a car to jerk when accelerating. Your vehicle may have a defective fuel pump or filter in addition to dirty fuel injectors. A broken fuel pump prevents the engine from receiving the correct quantity of gasoline, and a filthy air filter clogs the system, allowing an excessive amount of fuel to be fed into the engine.
