It's nearly impossible to diagnose a problem like this over the Internet, unfortunately. The first thing I would do is get the PEAKE Research diagnostic tool and plug it into the card to see if you can get a better code than the ones that they read at your local auto parts store. In general I would guess that these codes might be caused by a vacuum leak somewhere in the intake. Your car is now 15 years old, and I predict that some of the field are beginning to wear out. The default action of replacing oxygen sensors is a common diagnosis by sales reps at local auto parts stores. It sounds like the car may need some professional diagnosis have a qualified mechanic in order to get this problem fixed
