i don't know if i just notice this, but it's annoying. I'm getting this vibration when i'm cruising (ie let go off the gas pedal) when i'm accelerating away. eg. traffic light turns green, from stationary then moving away probably gear 2 or 3 around 30-40 km/h, if i let go off the gas pedal (not totally let go, but maintaining the speed instead of continue accelerating), kinda feel some kind of vibration. Don't know how to describe. Hence need your expert opinion what to check / replace.
