I found this while looking on the Nasioc forums. http://forums.nasioc.com/forums/showthread.php?t=569754&page=1&pp=25 Looks like my car fits the bill too, aparently mostly 03's. My question is which dealer is most likely going to say "thats normal" and which is going to fix the actually problem if it is indeed the issue. My symptoms seem identical to the ones described in that thread. I'll do some tests tonight but I'm pretty sure I have the same issue.
