hey dcg, whats confusing me is i never had the 153 or 212 errors before i replaced the front 02 and getting the 425, 435
I've been going through the archives and havent found anything definitive except checking all the resistance levels of both sensors.
It just seems strange when it says you have bad sensors to no sensors and both sensors have been affected before and after the front O2 sensor change.
When I had my front o2 changed it didnt look bad at all. Not carbonated or anything. Just tarnish with a rust looking thin coating... from the heat.
I think it may all be geared to the rear sensor. I'm going to end up poping that one out and taking a visual inspection of it.
Did you ever take your rear one out or have it replaced?
