While trying to diagnose my latest porblems, I was able to find the service manual (pdf) for the '02 i35.
Check it out if anyone needs it. It's pretty big, but so far has been VERY useful.I haven't been able f=to find a Haynes or Chilton manual elsehere, so I think it might come in handy.

It's several pdf's, and you will need all of them. The manual has embedded links, and some of the links are spanned across the different documents.
Enjoy!
