No luck guys. As soon as I got the Z home today, I asked my fiance to come out and check her out. She was very impressed with the car. I said, "well, you came outside to see it, might as well sit in it and hear her start up."
Immediately, when I press the start button, (like the very same moment) the engine rolled over and roared to life. And then, from the passenger's seat....a squeal. I just about gave myself whiplash to see what the noise was, and I see the look on my fiance's face. This squeal noise seems to please her. I focus back on the tachy and rev it up a little (about 5-6k rpm) and the squeal happens again. WTF is that? There she is again, she smiling. Weird.
