high idle

[HOLEIN1]

ive noticed that my MK4 gti has a bit of an erratic idle

when i say this it will idle anywhere between 1100 and 1300 rather than the 800 mark which i should, the needle also moves slightly up and down when at the lights

just wondering if there is any way that this can be reset or adjusted?

Scan on VAG-COM, clean out throttle body, reset basic settings!

Yep throttle body sounds right. Have a look here
