3.2 oxygen sensor issue
Yes, I searched and found good info but I still need to ask. Performed most of the 60K service on my '84 yesterday and when replacing the O2 sensor I found that the lower plug was broken. Pulled the old sensor, tried to epoxy it back together (sorry, had to try), that failed, so now the new sensor is connected normally on the upper, 3-prong part, but not on the lower, single prong part. Car ran like a champ after the tune-up with the O2 not fully connected. Any thoughts on how to proceed?
On a side note, the car ran great after the tune, noticeably better, but then today on the PNW Pelican XXX drive, after maybe 80 miles of driving, the car started to run slightly rough at idle and has continued to have a slight roughness at idle. Car still drives fine, just a new, different sound to the idle. Not a miss but almost a miss-like sound. Maybe a little rich too as it smelled rich after shut-off. Thanks in advance. Broken female end:  Broken male end with a dab of JB epoxy (fail):

it is toast, just get a male and female bullet style connectors and solder it on and use heat shrink, take carefull attention to the sheilding.
find a piece of hose same od of the clamp, slip it on to hold it in place.

Thanks Draco, I'll do that. It was already broken before I bought the car (PPI missed that) so it didn't seem to effect the way it runs.

To make sure about the shielding, take apart that crumbled connect to see exactly how it is assembled so you can duplicate the solder/connection, this connector supposedly takes air samples from the engine bay

Upon further review...
More searching revealed this thread that I had missed before:
O2 Sensor connector PM sent to Louie85 with fingers crossed. I love this place.

just make sure you address the shielding no matter what you do, it is critcial for the DME to operate the o2s properly.

Heck yeah, our euro brother don't even have a o2s :-)
But not too long, you will over work your DME because it was programed with it.

Do not solder the connector on an O2 sensor. The O2 sensor uses air pulled through the conductor as part of its operation.
Sounds weird and I know someone will cry "Bull!" so let's hear it from Bosch... http://www.boschautoparts.com/BAP_Technical_Resources%2FOxygen%20Sensors%2FO2Ins tallGDWEB09.pdf

BE911SC. The green wire coming out from the wiring harness is very short not much you can do there unless you remove the whole harness. You can try to crumble the rest of existing connector to get an extra 1/2 inch. I would just cut it at the end of the connector, carefully trim the shielding about 3/8 of an inch. Then strip the inner wire about 1/4 inch and crimp the electrical connector then secure with heat shrink.
