[Mk2] [Turbo] Not great on startup

[lightweightbaby]

Hey, had the car for about 7 weeks now, but only been driving it for about a month. Really enjoying it, just got a few small issues I was hoping somebody could help with!
When I start the car, and the engine fires up the whole car seems to jerk forward, not its not in gear haha! I Could this be worn engine mounts?
It also dosn't like the cold when first starting, and will idle 600rpm, is this normal?

Thanks for the help, Luke.
