my vsa light is on suddenly nd i cannot accelerateor low throttle response. why/

Don't chance it on this one. The vehicle is going into limp mode and is restricting power (most noticeable on hills when power is needed more). Take it in to a certified shop from the list below for an honest diagnosis and estimate by certified technicians. http://repairpal.com/honda-within-10-miles-of-brooklyn-new-york-11226
