Power loss issue
I could use a bit of help figuring out what is wrong with my car.
Car: 2007 Focus Hatchback S, Manual transmission
When throttle is wide open, accelerating in second (third) gear, once I reach about 40 (60) mph, there is an air rushing noise that gets loader and loader (very similar to what I would think forced induction would sound like). At about 45 (75) mph, it feels like I have hit the rev limiter with a sudden loss of power. If I'm only on partial throttle, this will not happen and the car will rev to redline just fine. Power seems just fine at lower revs. There is no engine light.
