Q: Car shakes for acceleration

asked by on December 13, 2016

when I hit the pedal then car shaking during speed increased. this issue just occur in low speed only or when car start to travel. shaking is only for few second then acceleration will run normal and smooth.

My car has 96000 miles.
My car has an automatic transmission.

Shaking or vibrating may be caused by many different things such as faulty spark plugs, poor fuel pressure or misfires. Other things such as a faulty idle air control valve may cause the engine idle to drop below the normal idling RPM which may also cause the motor to shake or vibrate more than normal. This creates a loss of power that resonates throughout the motor additionally causing other problems with ignition and fuel timing. Anytime a misfire is caused, this causes an imbalance in the motor which will cause the motor to shake or vibrate. The other issue that may cause this type of shaking or vibration is a broken engine mount. Engine mounts are generally rubber mounted braces that hold the engine in place to the chassis of the car. When these break or become weak or faulty, this may cause the engine to vibrate heavily. Due to the many possible causes of this type of shaking or vibration, I would suggest having an expert from YourMechanic come to your location to diagnose and inspect your vehicle.
