Check for vacuum leaks. Loose vacuum line hose or one that's cracked/split & also where the carburetor meets the intake manifold & where the intake meets the heads. If the vacuum lines are good, you can spray a little bit of carb cleaner or WD-40 around the manifold joints while the engine's running & if the idle changes suddenly, you just found a leak.

The engine's not under load in Park of Neutral, so what shows up when the vehicle's in Drive often doesn't show up in P or N.
