You need a controller as well as the sensor. Try doing a word search on
<EGOR> in the archives for a starter. A regular O2 sensor should not be
regarded as anything more than a switch that tells you rich or lean!

A sensor for a '93 to '95 Honda VTEC will be the right sensor for a lot
less money than anywhere else, (about $110, Jobber) but that does not solve
the controller problem.
