I have a 2k-auto-max with a little over 63k miles on it. Recently I have been experiencing a touble code #138(down stream O2 reading is high)I have been clearing it of and on but it still pop on every now and then. Car run fine though. Any of you guys having this same problem?

 

There is a TSB for it, check the FAQ, my dealer won't do it under warranty tho, so basically you will have to pay for it by yourself
