I studied the busdepot O2 sensor options after I sent my previous email, and
realized that the difference in price is not OE vs. after-market, but it's
whether I use the connectors I have or get an O2 sensor that comes with
them.

$100 is a lot to pay for new connectors!

Do they tend to be what's gone bad?  Or is it the sensor itself?  Is there a
way to tell if something's wrong with the connectors?  Why would I want new
ones?

I have been driving Matilda with the O2 sensor disconnected since the new
Boston Bob engine went in.  Put on 1200 miles, she's running great.  Then I
remembered that the O2 sensor wasn't connected, so I reconnected it.  Then
she ran doggy, low power especially getting going, and black soot in the
exhaust pipe.  Disconnected it again and she runs fine.  Which seems like
good evidence that the O2 sensor got fried when the old engine did.

But how do I know whether I need new connectors or I can just get the
sensor?
