Re: 2005 Failed Emissions
OK what I see looks like HC is near three times the limit and B1S2 and B2S2 (downstream O2 sensors on both banks) are at the max (should be under 50%}. Would want to instrument (Torque Pro can read all sensors in real time) but sure sounds like both catalysts are thoroughly ex.
ps dumb question but have you verified that both catalysts are there ?
