Black smoke usually relates to excessive fuel input. It sounds as though you may have an issue with your cold start system as the problem goes away once the engine has done a few miles and warmed up a bit.

Check the basics first: how is your air filter looking? Does it need to be changed.

Hmm, sounds like a pesky electronic problem. I remember when it was carbs and points, those I could fix. Electronics are just mad. Might be worth having an independent Toyota specialist or main dealer run a proper diagnostic for you. Worth telling them to only work for, say, up to an hour/up to a set amount of cash though, just in case they spend all day looking at it.
