96 Audi a4 2.8L sohc just recieved p0432 catalyst code I replaced my rear 02s within in the year so bad cat?

 

Bumppp

 

I don't know much about 2.8s but a p0432 is the air/fuel being retarded. And if I remember correctly, the o2 sensors before the cat are the air/fuel o2s with the back being there just incase the cat craps out, so you may need to replaced the front o2 sensor on whichever bank it is saying it is (I think p0423 is bank 2). But I would get a second opinion from a more knowledgeable 2.8'r before spending the money on a new 02

 

Alright I cleared it waiting for code to come back

 

had the same thing changed coil pack and it went away for 200 or so miles then came back, i was thinking about spacers for the 02s or just buy another audi

 

Bad cat. Drivers side.
