Sweet, thank you! Looks like I'll be replacing my O2's (there originals with 113k miles on 'em). As far as the other two things. I guess I'll have to pull out my Bentley to do a little research and find out how to fix them, eh?
Go ahead, ask me a question... Check out the CopTalk thread in the California forum

Thank you Sam
