I had the same problem on a Rover. There was a leak in inlet manifold that was caussing the problem.
To verify, spray some sealant to temporarily seal the inlet manifold .and the eratic idling should disappear for some time.
If it does, you know there is leak in inlet manifold which you can take of and refit with a new gasket.

1986-1989 Honda Accord with Carburetor have a very bad habit that is little known even by most mechanics but easily fixed at home. The vacuum port on the choke opener that is connected to the intake manifold and both vacuum ports on the fast idle unloader get plugged up with nasty hard carbon almost as hard as metal. When this happens the choke sticks closed and the idle sticks on fast idle when the engine is cold and nobody can figure out why. All you have to do is attach a small drill bit to the end of a flexible socket-driver extension and put it in a variable speed drill that will let you run it real slow and carefully drill out the vacuum ports that are plugged. After they are nice and clean use a vacuum pump tester to make sure the choke opener and fast idle unloader are working before putting it all back together. It's amazing how much better the car runs after cleaning out those ports.

SOURCE: How to Adjust idle RPM for a 2003 honda accord. some people were talking about a screw on the throttle body. but I can't find that screw. How do you go with adjusting this and where to find it ?
First, you shouldn't adjust the idle. If the idle isn't correct, that means there is an issue somewhere - not that the idle needs to be adjusted.
There isn't an adjustment screw. To adjust the idle, you will need to move the TPS (Throttle Position Sensor) forwards or backward. To do this, you will need to remove the tamper proof bolt and replace it with one that can be loosened and tightened.
