Hm... I just had my throttle body replaced and when it's actually working, the car goes so smoothly. After a week of driving, I think the throttle body is acting up again. It feels as though it's "pulling back" (again) a little whereas when the throttle body is working, you can really feel the car moving without the "pull back" effect. I'm wondering if anyone else has this problem even after having the throttle body changed.

I have an 05, by the way.
