Part 1:  Use something like Liquid Wrench or PB Buster
- something that penetrates.  I don't think oil will
work that well.

Part 2:  I don't believe a disconnected O2 sensor will
cause these problems.  I have been running with a
disconnected O2 sensor on my 84 for over two years and
it runs like a champ.  Disconnected O2 will cause you
lose some fuel economy.

Part 3:  Water-cooled up to 85 are Digijet.
Everything afterwards is Digifant.
