If your sensor has 3 wire, make sure you get a three wire universal. And when you hook it up make damn sure you pput the right wires together. The only diff really between a universal and an exact fit is the exact fit has a connector, and the right length of wire, where as the universal has a crimp connector. Als if you go universal, there should be some heat shrink sleeves on the wires. Make sure you put those sleeves over the connectors, and runn a lighter over them to shink them down. Shorting out those wires could be realy bad.

Is there any sealant used for the o2 to seal the thread on is it just a really tight thread?

An O2 sensor should come with a dab of anti seize on the threads. If not put some on! This is one thing than is a real pain to deal with if it breaks. Yeah, been there done that didn´t like it. be careful not to get any anti seize on the slotted portion of the sensor. just a little on the threads is all you need.

I am not running an o2 sensor. Makes my car die when I hook it up and it does the same thing with a new one. I think my ecu is fryed someplace... But Oh well drive it till it dies and fix it again...
