I had the same exact problem for 15k miles but worse, my rpms would even climb with now accelerator. I am at school now, but i will tell you what you need to get done at the ford dealer when i get home. my car feels new again and i dont have the probelm. btw, dont go too long with out fixing this problem because your clutch will get worn. if you are shifting and the rpms dont go down, you are being thrown into every gear and thats not good for the clutch, beleive me, my clutch engages really high, ill get back to you...
