While stopping or stopped for traffic light(s), with foot on brake, engine revved up to 2k rpm without any action on my part. when light changed, and brake was released, acceleration and car performance became normal again. this has happened three separate times in the past six weeks. in addition, turning the a/c off or on had no effect on engine rpm. note: during the anomaly, if transmission was moved from d to n, engine would rev up to 5k rpm, and would drop back to 2k rpm when transmission put back into d all this happened with foot still on the brake. for the record: car was taken to honda dealer twice for this anomaly, the memory dumped, and no data found. honda claims there is nothing wrong with the car. *tr
