In looking at the service info, I see no special procedure for relearning idle after a sensor replacement, or at any time for that matter. Make sure the vacuum hose is fastened to the sensor correctly, or it will run full rich, and/or the vacuum leak will cause idle problems. You may also try disconnecting and shorting the battery cables together for a minute or so. Reconnect and re-evaluate the performance.
