Welcome!
This section is really for welcome & introductions so I'll move your post over to General Tech.

Oil in the sparkplug tubes means you need a new valve cover gasket. Maybe also some seals further down in those tubes, but search for "sparkplug tubes" or something like that. Oil causing misfiring is probably the reason for flaky idle & stalling.

 

I agree you probably need a new valve cover gasket but u might have some issues other than that. I would check your distributor cap and rotor its a common problem on hondas for them to get old and crap out. I would also check your map sensor and maybe you might need an idle adjustment wich is pretty easy to do
