1. Misfiring engine. When an engine misfires, it means that one or more of the cylinders are not firing properly. This can cause the engine to vibrate, as well as create a jerking or shaking sensation.
2. Engine mounts. The engine mounts are rubber or metal components that attach the engine to the frame of the car. When the engine mounts are worn out or damaged, they can no longer effectively dampen the vibrations created by the engine. This can result in the car shaking or vibrating when the gas pedal is pressed hard.
3. Driveline problems. The driveline includes the transmission, driveshaft, and rear axle. If any of these components are damaged or worn out, they can cause the car to shake or vibrate.
4. Wheel alignment. If your car's wheels are not properly aligned, it can cause the car to shake or vibrate at high speeds.
If you are experiencing shaking or vibration when you press on the gas pedal, it is important to have your car inspected by a qualified mechanic as soon as possible.
