A4 B7 Avant, 3.2 V6

99% of the time, the car idles fine. Every once and a while it will blip up to 1100ish, then down to 700 then back to normal idle. It all happens within 2-3 seconds.

Also, sometimes (most notably going into 2nd and 3rd gears) you can feel a bit of gap in the power. The accelerator needs to be pushed down a little bit father before you feel anything. This part is barely noticeable and maybe I only notice it because I drive it every day.
