Step 1; change the plugs, the oil, the filters, then check the fuel pressure regulator. This is a small metal barrel on the manifold at the back of the engine, with a vacuum lead hanging off it. Make sure the vacuum lead to it isn't damaged, and all vacuum leads going to and from the engine.

Another is the Idle Air control valve on the throttle body. Make sure it's secure and moiture free (4 pin plug on it)

Take off the air intake duct from the air cleaner, and while the engine is running, spray the throttle inside with carburettor cleaner. This will get rid of any residual carbon/sluge or other garbage clogging up its throat. If it still runs rough after all this, check each electrical connector on the engine one by one.

As a final note, if the "roughness" has a "rhythm" then it may be your ignition coil pack. If any one of the coils on the ignition is suss, one or more of the plugs may not be firing properly.

The inside of the Idle Air Control valve is the one thing most likely to make it idle rough. You'll see it as a small hole in the side of the throttle body. When it gets choked up with carbon, it will do this, as the engine computer relies on it to control idle fuel mix and idle rpm

You'll find that there's almost enough info here to strip and rebuild a VN, almost to the last nut and bolt. Even if the info isn't there. someone's bound to come up with a solution
