The top motor mount is worn out. It would have helped knowing the car's year, make, and model, but, if your car's engine shudders after it is warmed-up and running idle, then it is probably a symptom that your vehicle needs a tune-up (i.e., new spark plugs (assuming it isn't a diesel), change the timing belt or chain, etc) or that you used a grade of gas that is not suitable for the vehicle (in some cars, even premium gas may throw off a car's timing) or the transmission modulator (or similar) is malfunctioning. Unfortunately, without seeing the vehicle, there is no way to determine exactly what the problem is, so take the car to a qualified mechanic.
