Before you put it in a garage have a look here:

Blocked breather jet and hoses are a common problem on the 2.0l.  I had it with mine, cutting out at low revs, erratic idling etc.  Cleaned them out as per this guide and it made a world of difference.

Total costs is about £20 plus the time to do it.  Thats to buy the IACV and Throttle body gasket (if you take the throttle body off as well) and some carb cleaner.

Cleaning the throttle body info is here:

If you take the rear air intake hose off (5 minute job) and look in the top of the throttle body, if its really dirty then that is a good sign the breather jet etc is blocked as the air is not going around the system correcly and oily fumes get into the top of the throttle body fouling it up.
