Lincoln/Mercury Repair: 1997 Mercury villager idles poorly, mercury villager, coolant leak

Question
My wife 1997  Mercury Villager (illinois) idles poorly.  So far the fuel filter, throttle body cleaning, spark plugs, and a repair to a coolant leak near throttle body were performed.  The car still idles poorly (rough) mainly when the car is warm/hot.  The rough idling goes away when the car is very cold or when the accelerator is slightly pressed.  Thanks
