had same prob on mine ages ago. turned out to be the o2 sensor (lambda sensor) get vag com on to it, that will give you more details

[mani12354]

where is the lambda sensor and isit easy to change?

[golf newbie]

Lambda sensor is probe attached to the front pipe.

Worth disconnecting the lambda sensor see if it runs better.

The connector is above the rear engine mount.

[mani12354]

where can buy one from and how much isit? 

[golf newbie]

They about 50-70 quid from gsf etc.

Try disconnecting the sensor first if it runs better without the sensor then you know thats the problem.

  expensive  umm so i got get under the car  lol thanks for that 

[golf newbie]

You dont have to get under car.

The connector to lambda sensor is on the left hand side of engine bay should be near the master cylinder its a oblong connector just disconnect that and run engine.
