throttle body" fuel", cooling system separate.

On a 3.8 engine the throttle body and upper plenum contain coolant. There is a gasket between them that could leak. More important the upper pleninum on the 3.8 engine often develops a leak near the EGR inlet which is in the area you are concerned with.

Look for a vacuum leak. With the engine idling, anywhere you have a vacuum hose attached, Spray some throttle body cleaner at the connections and see if the engine idle picks up even just a bit. If it does, you have a vacuum leak. After checking if you do not find anything, at least spray some throttle body cleaner in the throttle body and clean the throttle blade up. Also try the Idle air Control Valve Located on top of your throttle body, or even the throttle position sensor
