I have had my STI now for about 3 months and absolutely love it. However, I have noticed that when reaching about 95 MPH there is a wierd noise and slight vibration from under the hood similar to that of the small grooves at the beginning of the shoulder on the highway that let you know your drunk and going off the road, or falling asleep. The noise and vibration are not as harsh as the bumps. The car returns back to normal operation when I reach about 103 MPH and continues to operate fine the rest of the way up to......145. It does this no matter what gear I am in, it still happens. Does anyone else have this problem or know what it may be.
