    I have had these codes popping up for quite a while. The engine runs great. I changed out one of the cam shaft sensors on the advice that it would clear the 0420 code also when I had it tuned but didnt know there were more than one. Has this happened to anyone else? I am now getting a 0430 code also. Where are these sensors located? Should I go ahead and change out O2 sensors also?

    thanks,

    You have bad catalytic converters. Replacing o2 sensors will not fix this. Search the ole interweb on o2 sensor spacers. This will be an inexpensive fix, unless you would like to shell out several hunerds for new cats.....best of luck.
