TheDuff Posted May 18, 2018 Report Share Posted May 18, 2018 I have 2004 3.2, I had fault code P0430 which is Catalyst System Below Threshold Bank 2, which I thought maybe down to a slight leak on the offside exhaust. I cleared the code and now about 3 weeks later fault code P0420 has come on which is Bank 1. Any ideas on where to start off looking for the issue.
