'01 Accord error codes P0420 & P0141
My check engine keeps coming on and off. Today I took it to Autozone and they gave me error codes P0420 and P0141. I put a new CAT on about 10 months ago, Could it be my secondary o2 sensor thats going bad? I need to take an emission test soon so I need to fix this as soon as I can. Thanks for your help. BTW its a 2001 Accord 4 cyl.
