first of all, get it straight buddy. VTEC is honda's engine management system. V-tech is a phone company. Remember that.

As far as the vibration goes, i got a 2002 ex coupe I4 5-speed and mine is hella smooth when at idle. Sometimes, i dont know if the engine is on or off cause it runs so smooth. I think u should check ur motor mount first and work ur way from there. However, u shouldnt feel that vibration, esp on that new car.
