Code P219A relates to a fuel/ai ration imbalance, which may be caused by any number of things such as faulty喷油器, low fuel pressure, a faultyEGR valve, a faulty蒸发罐or intake leaks, creating a lean fuel condition in most cases. I would suggest having a professional from YourMechanic come to your location to take a look at the vehicle as this may require some specific diagnostic tests to narrow down the cause.
