Engine starting to vibrate

I bought a Integra VTi-R (or as most of you call it GSR, i'm from Aus) about a week ago and when i first bought it, I could barely tell the engine was one. But now after a week the engine is vibrating a bit more and you can hear/feel that the engine is on. It's not a big problem but I would like to know what is causing it.

look for damaged spark plug wires or fouled plugs or maybe even torn or broken motor mounts

is it vibrating all the time or just when at idle?

I first noticed it at idle but when cruising at higher speeds it does tend to shake a bit more than before. It's not to the point of "oh shit my engines gonna fall out". Its more at the stage me wanting to prevent damages to the engine if you get what i mean.
