What causes strong car jerking sensation?
3 Answers
Strong car jerking sensation may be caused by insufficient oil in the engine. Below are relevant explanations for the engine yellow warning light: Sensor issues: Sensors including water temperature, crankshaft position, air flow, intake temperature, oxygen sensors, etc. When these sensors are damaged, have poor contact, or experience signal interruption, the vehicle's ECU cannot accurately obtain engine data, which will trigger the engine warning light. Maintenance issues: Poor engine maintenance is the most common reason for the engine warning light to illuminate. Vehicles have specific maintenance cycles. If owners fail to perform maintenance on schedule, coupled with poor driving habits, it will increase the operational burden on the engine, ultimately triggering the yellow warning light as an alert.
I've experienced this situation with my previous car. When accelerating, the car felt jerky, as if being pulled back by something. The reason could be aging spark plugs or issues with the ignition system, causing the engine to run unevenly. That time, I replaced the spark plugs, and the car immediately ran smoothly. Another common issue is dirty transmission fluid or transmission failure itself. If an automatic transmission car has strong jerking during gear shifts, it's necessary to check the fluid level or change the oil immediately. If ignored for a long time, it can also wear out engine components, leading to higher repair costs. I suggest going to a professional repair shop for diagnosis as early as possible. Don't wait for small problems to become big troubles. Pay more attention to these details during regular maintenance.
When I first started driving, I experienced the same issue - the car had noticeable jerking movements that really unsettled me. After some research, I learned this could be due to dirty spark plugs or incorrect gaps affecting ignition efficiency, or possibly a clogged fuel filter causing uneven fuel supply. I can start by opening the hood to check the spark plug color - if they appear blackened, I'll replace them. Alternatively, I should inspect if the air filter is too dirty. For safety reasons, if the jerking occurs frequently, it's best to avoid highway driving and take the car directly to a repair shop for technicians to examine the electronic systems or sensors. Don't delay, as this could prevent potential accidents.
