So I've been getting p0431 for about a month now too. I can't find a mechanic willing to pinpoint the problem. I seems simple if you have the right tools. If it's just the o2 sensors I'll be fine and if if it's the cats that's fine too but I want to know for sure so as to not waist my time. Please let me know how it goes for you.Watched the check engine light come on again... been popping p0300 and p0431 off and on for the past three weeks. Changing one thing at a time and then waiting for it to come back is getting tiring. Think i may have finally beat the random misfire code p0300 as only p0431 (catalytic converter) popped up this time. 02 sensors on the way and then i suspect ill be replacing the shit cats chrystler decided to throw in my baby.
