Mitsubishi montero limited 2001 w/ intermitent chck engine light giveng me P0431 code and the truck goes on for another 1,000 or so miles. Just passed emissions without problems, althought muffler/exhaust place advised me to change cat anto2 sens because otherwise it would not pass emissipns. Should I worry about code?
have the same problem?
