Welcome to the forums. Is there a reason the O2 sensor hasn't been changed? It isn't difficult, nor expensive, and can have a direct affect on how the car starts and runs. It gives the computer information that will either lean out or enrichen the fuel mixture at specific times. That would be my first stab.
