What are the reasons for the car jerking and not getting enough fuel?
4 Answers
The reasons for the car jerking and not getting enough fuel are: 1. Fuel quality issues: If the fuel used does not meet the required standards and cannot meet the engine's operational needs, the output power will decrease; 2. Faults in the intake system: Slow response when accelerating may require checking the intake valve, intake pipes, and air filter for blockages or damage; 3. Power system malfunction: When inspecting the power transmission device, check whether the transmission is slipping or has gear engagement issues; 4. Sensor malfunction: This can cause a slow response when accelerating and requires professional repair; 5. Ignition issues: Problems with spark plugs or inaccurate ignition timing, it is recommended to visit a 4S shop for repairs; 6. Driving habits: Pressing the accelerator too quickly or too slowly can lead to a sluggish throttle response, so it's important to apply the right amount of pressure.
In my years of driving experience, when the car struggles to accelerate and sputters, it's usually due to fuel supply or ignition system issues. For example, a clogged fuel filter preventing the fuel pump from delivering fuel, or spark plugs with excessive carbon buildup causing delayed ignition and engine power loss. Sometimes it's a blocked air filter leading to insufficient air intake and improper air-fuel mixture. Ignoring these issues can cause more severe engine damage and even skyrocket fuel consumption. I recommend first checking simple components like whether the spark plugs need replacement or if the fuel filter is dirty. Regular maintenance can significantly reduce such problems and avoid breakdowns that disrupt your journey.
The car started jerking and shaking as soon as I drove off, and that time it almost scared me to death—it was due to aging ignition coils. Simply put, the ignition signal was interrupted, causing the car to lose power. I’ve also experienced fuel system issues, like a failed fuel pump in the tank or clogged fuel injectors, which cut off the fuel supply. Regularly replacing the fuel filter can prevent this; otherwise, minor issues can turn into major headaches. Pay attention to any unusual noises while driving and address problems early—it saves hassle and keeps you safe. Repairs aren’t expensive either; just replacing a few parts will do. But if you ignore it, engine wear increases, and repair costs will skyrocket.
When encountering engine hesitation and stuttering, the first things that come to mind are faulty spark plugs or a failing fuel pump. Rusty spark plugs cause slow ignition, while a weak fuel pump fails to deliver sufficient fuel. Checking the fuel system and ignition takes about half an hour to resolve. Dirty air sensors or ECU malfunctions can also cause hesitation. Don't overlook minor maintenance items during routine servicing to keep the vehicle running smoothly.
