advice please :)

Right basically when I'm driving, the car feels pretty sluggish under 2000 rpm and once it goes past there it seems to have a little boost and then feels fine. It usually happens when there's more that one in the car, it can't just be the weight because its only recently started. Also it seems to be a bit sluggish when starting up sometimes, a mate suggested it could be something to do with spark plugs so this could be the problem?
I'd appreciate any advice.
Thanks in advance

I haven't a clue myself haha, I have a breif understanding of how engines work but I wouldn't know where to start when fixing one. I think ill check my plugs and do a general service of it, probably due some oil tbh haha
