Hello guys my name is Nelson and I had just recently purchased a Honda S2000. I fixed most of the issues the only one left is a very strange sound that I hear While the car is in idle or in any gear does not matter if it is warm or if it is cold the sound is constant. It almost sounds like like a vacuum leak but I have checked all of my hoses and everything is in great shape. The car drives flawlessly and has no hesitation throughout any RPM range. Here is a link to the video that I made for the sound.
