I dont think I can get a sound clip as the car only makes the noise while in gear. You can really hear it as the car drives close to a barrier, wall, or between buildings as the sound can resonate.
If you make an s sound, much like the beginning of the word "snake", and hold that noise- thats what it sounds like! Again, the noise goes away as I accelerate out of the 2500 RPM range, give or take. As the car shifts, however, it hits that sweet spot of about 1500 RPM while cruising. Only when the throttle is depressed does it make the noise- not while the car is coasting. What the heck could it be? Thanks for your input Knight
