Noticed a strange noise coming from my 02 1.6 Focus, especially when the car is cold. When accelerating in 1st and 2nd gears between 2k-3k revs, there is a change in engine sound and it sounds very deep and much louder than it does throughout the rest of the rev range.
It's hard to explain, kind of louder, deeper and echoey. Doesn't sound right to me at all.
Any thoughts?
