eratic idle at start up.. fine once warm... 400 1989

If you have an air pump, US spec cars have them to pump air to the exhaust which helps the cat converter to warm up. It stops when the engine warms up.
There will be a hose coming from the air filter, usually down, and goint to an electrical pump/fan, then another tube going from it to the exhaust.

Your car sound like it is running too rich on startup. Cleaning the throttle body is a good idea.
