You must have a 2006. There is a reflash available for your car (I think).

Your drive - by - wire throttle needs a reflash.

The VIN range is 2HGFG2...6H700001 - 2HGFG2...6H707606.

I'm not sure if this is car specific...but its physics. You have something spinning with a certain load and you take that load away it will spin faster (increase in rpm) momentarily. This has happened in every manual car I've driven.
