What Causes Severe Car Vibration When Accelerating?
1 Answers
Reasons for car vibration when accelerating: fuel line blockage causing poor fuel supply, air intake system leaks or blockages, damaged ignition coils and spark plugs, excessive carbon buildup in the throttle body, faulty fuel injectors, clogged fuel filter, etc. Below is relevant information: 1. Fuel system issues are generally caused by fuel line blockages leading to poor fuel supply, manifested as engine vibration, unstable idle, or stalling while driving; additionally, fuel pump failure can also cause engine vibration. To diagnose fuel pump issues, disconnect the fuel line and check flow rate and volume. For proper operation, the engine requires sufficient air, adequate fuel, and a well-functioning ignition system. Problems in any of these areas can cause engine vibration. If the intake system has leaks or blockages, acceleration vibration will occur when pressing the accelerator. 2. In the engine ignition system, ignition high-voltage wires rarely fail, so the main issues usually lie with ignition coils and spark plugs, as they are wear-prone components. When spark plugs degrade or inferior-quality spark plugs are used, it can result in weak acceleration or acceleration vibration. 3. The automotive fuel system is extensive with many components, and any abnormal or faulty part can cause engine vibration during acceleration. Examples include excessive carbon buildup in the throttle body, faulty fuel injectors, or a clogged fuel filter. In summary, car body vibration while driving is not a minor issue. Unless it's normal gearshift shock, it should be promptly inspected at a professional repair shop or 4S store.
