In order for a car engine to runs smoothly, each cylinder inside the engine must fire in the correct manner. However, if there is an engine misfiring on one of the cylinders the engine balance will be thrown off. If the engine cylinder does not fire as it should be there will be an excessive engine vibration which can also cause the entire car to shake as well.

There are a lot of causes of engine misfiring, but the most common cause is bad spark plugs or spark plug wires and a worn distributor cap. When one of these causes occurs it will affect air/fuel mixture firing inside the engines cylinder. Another cause is a burned valve. Engine with a burned valve will cause an improper engine compression on the affected cylinders and this will result in an engine misfiring.
