Dan,
I just replaced the front O2 sensor on the '99 Legacy Outback w/ 122kmiles.
The check engine light would come on for a while and then shut off. I think
I remeber the code being P420, said catalyic efficiency was low or something
like that. Replacing the front O2 sensor is a lot cheaper than replacing the
catlytic convertor. Light hasn't come back on yet.
