Hi, is it normal for the NSX to vibrate a bit rough during cold start up? It eventually goes away when the RPM drops after few seconds of warm up. Is this normal? Also, when I blip the throttle while waiting for the traffic light (between 1000~~1500RPM), the engine seems to vibrate a little more. Anything above or below (idling) that, it runs very smooth. It's a one year old car and has a little over 6k miles.
Thanks,
Thanks,
