You need to connect an analog dwell meter to the test port under the plastic cover in the engine compartment to "see" what the lambda system is doing under differing conditions. Everything you need to know is in the archives, try searching for CIS lambda. Stumbling and stalling after cold start is usually caused by weak mixture from vacuum leaks, the vacuum retard and using other than BOSCH normal spark plugs. The O2 sensor is irrelevant to cold starts but the ECU and pulsing FV are not, they must be at the default duty cycle.
