My 2006 Honda Civic si has an issue with "hanging revs" that even after the release of the gas pedal the rpms seems to stay steady for 1-2 seconds. The inability of the dbw system will eventually lead to early clutch failure, also there is surging and jerking in 1st-2nd gear. I must say that it makes me very nervous to drive because I can't predict what the car will do. The car also seems to have a notchy, stiff, and grinding 3rd gear that won't seem to go away even with recommended fluid.
