I did a search on the dreaded P0420 code so I do know that likely my front O2 sensor could be bad / or I could put a spacer in the rear.
The Vag-Com states "P0420 - Catalyst System; Bank 1: Efficiency Below Threshold". Does this tell me which sensor that the car is having issues with which could narrow down my problem?
Thanks everyone - I want to fix the problem since we are selling the 2002 subie outback sedan, been a great car but wife needs a mini van. She still wished that Subie made a mini van.
