Fuel system diagnostic help.

Cap was old, but nothing really odd.  Rotor was replaced pretty
recently.  Plugs seemed fine to me, but I wouldn't know the
difference.  Oddly enough, after test driving for the first time, the car
still had problems.  Then I drove the car again to test the O2 sensor
under load, and it seemed to do fine.  I am thinking that mabey if I am
really lucky, it was just a loose connection to the O2 sensor....

Now I have two new fun problems.  1. Battery or alternator - I suppose the
battery (if I almost stall it, the lights quickly dim).  2. Headlights
switch is stuck in the on position.  I can get the lights off, but it
doesn't click into place.  Ugh!
