URD made a 02 sensor calibrator for early year 3rd gens, but when installed on the later year runners it didn't work right (This calibrator was removed from their site about two weeks ago, it was called the ESC1) The product that I am now running works on all the 3rd gen 4runners equipped with two 02 sensors.
Edit: Dale, I noticed that you have a 93. Are you sure you have an AFR sensor? Maybe running the AFR calibrator on an 02 sensor is what's causing your open loop issue.

Ok gotcha. Pretty sure about the A/F ratio sensor, I removed it from a 2001 Tacoma, along with the engine, transmission, and ECU. All came from the same truck with only 27,000 miles on the ticker. All looked to be factory and I labeled the front and rear to keep them from getting mixed up. How could I tell for sure?
