Q: Car shakes and stalls when I press the accelerator.

asked by on January 04, 2017

Hi, My car shakes a lot and feels like it is going to stall. And when i tried driving it and press the accelarator it feels like it is going to turn off or even actually turn off. I change the spark plugs, air filter and clean the air intake and it is still the same problem

Thank you

Hello There, Shaking or vibration 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. I would suggest having an expert from YourMechanic come to your location to diagnose and inspect your vehicle.
