It's been a while since I been on this forum but I'm still in the LS family. I recently purchased another LS....this time a 06 v8 with 110k miles on it....I've been driving it as my DD since I bought almost a month ago and no issues. On the way home I got the dreaded CEL. Went to O'Reilys and they pulled up three codes, P0430, U1073, and U1262. I know the first code has to do with the catalytic converter not operating at optimum setup. I brought this car from a private owner and it "seemed" taken care of. If you look up under the hood you can see several parts replaced.
Where should I start?
