Well, apparently the I30 section is not too active.
I just inherited a '98 yesterday, so I will be doing a lot of "finding out" in the next few months. I know that doesn't answer your question, but I did see a post indicating that the I30 is highly similar to the Maxima mechanically. Perhaps someone in those forums have stumbled across the same problem.
Good luck with your research and post your findings. Need to knock the cobwebs off of this section.
