It means you need to stop swapping parts and take the car into a shop for PROPER diagnosis.

It means thet the O2 sensor behind the catalitic converter is sending a signal. could be connector has also gone bad from changing it or the wire is shorted. any other codes such as misfires??? Go to Audiforum.com ask questions there they will help with the diagnostics. You could bring it to the dealer but if you don't get used to repairing this car on your own it will empty your pockets. If you are mechanically inclined they are not as bad to work on as the people who have never owned say :)
