I have a 2000 Sienna with 160,000 miles. Received Diagnostic Code p0420 -- Catalytic Converter about 6 months ago. Had the cosde reset and ignored it and it diodn't come baclk for 6 months until yesterday. Same code. Should I do the same thing and ignore it, get the converter relaced ($1,500) or buy a new car? Thanks for your thoughts.
