Exactly, this is a common problem. You get used to how speedy a car is, and after time it feels slow. I went through this very same problem, and thought something was wrong. Everything checked out ok, did a valve adjustment. Might want to try cleaning your air filter out, that could cause it to be a little sluggish, I know it does on my car.
