O2 Sensor Disconnected
 

I was replacing my rear hood struts today, and I noticed that my O2 sensor wasn't connected. When I looked at the connection piece (the plug that the O2 sensor attaches to), it was broken.

My questions are:

1. What effect does this have on the engine?

2. How do I go about replacing that plug. I didn't get a close look at it, but my initial thought is to get one from a parts car and splice it on.

leave it that way- it works better without it.

bump, I have an 80 with the same situation.
