Has the car always been like this or it recently started doing it?
If it has always been like this then i think you just need to get used to it. Usually Honda 1.3 has a slow/sluggish response in 2nd gear if you change gear before 20 kmph. Either way, take it back to Honda and tell them how you feel. If they tell you to put Hi-Octane - don't fall for that BS.
