Tps could be on the fritz and so could be the MAF sensor, best place to start is a good service if you havnt done one in a long time, then start searching for the problem if it still exists

vaccume leak probably cracked hose somwhere. vw like to do this when the crank breather has a craked or loose bung in rocker cover.

Nah your both WRONG! ''and im right'' tehehe
Its the idle control valve thats faulty and needs a clean or replacing. Try removing it and soak it in brake clean 5-6 hours then re-fit before buying a new one.
