What Causes Car Vibration When Accelerating Hard?
2 Answers
The reasons for car vibration when accelerating hard are: 1. Excessive carbon buildup on spark plugs or prolonged usage; 2. Heavy contamination of throttle body and oxygen sensor; 3. Faulty fuel injectors; 4. Malfunctioning fuel pump causing poor fuel delivery; 5. Clogged fuel filter; 6. Bent or broken drive axle; 7. Worn or twisted spline gears. Solutions for car vibration when accelerating hard: 1. Replace or clean spark plugs; 2. Clean throttle body and oxygen sensor; 3. Replace fuel injectors, fuel pump, and fuel filter; 4. Inspect and repair drive axle and spline shaft.
Recently, I've noticed significant vibrations in my car when I press the accelerator hard, especially during high-speed acceleration, to the point where the steering wheel shakes. This makes me quite uneasy. Reflecting on this, such issues are often caused by problems in the engine's ignition system, such as worn-out spark plugs or faulty ignition coils, leading to uneven engine operation. It could also be due to wear in drivetrain components like the drive shaft or CV joints, which cause increased vibrations during hard acceleration. Additionally, unbalanced tires or aging suspension parts can affect ride smoothness. If the vibrations are more noticeable at specific speed ranges, say above 70 km/h, it might indicate that the tires need rebalancing. I suggest first checking simpler areas like tire pressure and tread wear. If that doesn't resolve the issue, take it to a professional shop for inspection without delay to prevent the problem from worsening. Driving safety and comfort are paramount, and I always address such issues promptly when I encounter them.
