Did you check the signal wire to PCM continuity? Also make sure the O2 heater is getting voltage.

Welcome to AF.

Check the wires to that O2 from the PCM to the sensor.
Thier must be a break in the wire if the sensor is a new one. OR the plug is not making proper contact.

Though the stalling could be something else.

Hope that helps!
