Sometimes the engine will misfire on idle. The sensors that read air-fuel mixture will malfunction, and the fuel mixture will get messed up. A leaky head gasket is the most common source of the idling problem, and it will cause an uneven idle and can even shut the engine off on idle.
A small amount of excess fuel in the cylinder is most likely to cause misfires at idle because the cylinder is most sensitive to small air-fuel ratio problems at idle.
A car is very balanced when manufactured and often has balance axles and different tricks to get as few vibrations from it as possible. The cylinders are important to the balance of your engine, so if one of them isn’t firing, it can create an imbalance, and this can cause heavy vibrations inside your cabin when accelerating or when idling.
