Mystery "whirring" at 40mph
For the last month or so, I have noticed a higher-pitched whirring noise coming from my car that I can't seem to diagnose. The noise is faint and can only be heard from 40 to 45mph and it only occurs when I am on the throttle. If I let off the throttle, the noise goes away. I have produced the same sound in 4th, 5th, and 6th gear (6MT), so I have ruled out a transmission-related issue. Once I accelerate beyond 45mph, the sound goes away.
Has anyone else had a similar issue? I have searched the forum multiple times and haven't been able to find a potential fix... Any help is greatly appreciated!
