Mine does this exact thing...especially after a long stretch of high speed driving. Sounds just like knocking or detonation. From what I've heard, it's sometimes due to the ECU having adjusted the fuel/ignition curve to the high speed/rpm driving, and not having had a chance to adjust back to low rpm driving, causing the knocking when you first press the gas. It apparently take the ECU a few minutes to adjust to driving conditions. Of course that's just my opinion, I could be wrong.
