I heard it on sunday while coming back after seeing heather (hzl_eyed_grl) on saturday. Anyway I found a small whine when I turned on the lights during the day. This evening while coming back home after dinner at my parents place, I accelerated past 30 in 2nd and I could hear this airplane sound, goto 3rd it did that too, then at 4th it went quiet but when i got to 70 it started again. The car has done 100,000 miles (last sunday on the way back it crossed over)and it is not due for service for another 1000 miles. Any ideas though.. the car is running fine otherwise.
