What is the trouble code you pulled from the ECM. If that's what made you think you have an O2 problem.

Have someone check the basics:
- stored trouble codes (warning light does not need to be on for a code to be stored)
- vacuum leaks
- throttle body (check for dirt build-up, clean and adapt (if applicable)
- temperature sensor (correct resistance when cold)
- fuel pressure
- fuel flow (demand from the engine) is different when the engine is warm. Maybe not enough when cold.
Etc.
Too many things that could be at fault that I / we can not check over the internet.
