370z rough start on occasion

[hansoac]

Yet another issue I am posting on here for some opinions (i think it says great things about our community and the ppl on it though)

So my z will start up fine after it sits overnight, however, lets say I drive it to the gym and it sets for a few hours. When I come out to start it, it will start to turn over and tick a couple of times and takes like 5 seconds or so to start. It doesn't do this EVERY time, probably 3 out of 5 starts. It sounds horrible and people look like "Nice car but what the hell is up with it starting?" It is quite embarrassing and I am wondering if it is causing any damage. I took it to the dealer but it wouldn't replicate. I attached a sound clip as I was lucky enough to catch it today. What do you guys think?

you might need windows 7 to play it or a codec. I am going to try to record it with video to put it on youtube.
