    Hold the Line! If you are not holding the line, abandon your ship. Destruction is inevitable without more to hold the line!
    My guess is the ECM was "use to" seeing the incorrect results from the defective oxygen sensor, so when it started getting the correct input, it "thought this must be wrong". I would put the new sensor back on, disconnect the battery to reset the ECM, then see if it comes back.
