There may be a vacuum air leak causing this problem. If you have a idle air and EGR valve check them also for trouble.

I have seen this problem on many golfs and jettas, there is a rubber vacuum hose about 3/4 inch in dia, at the back of the head on the #4cyl beside intake manifold,this hose often fails due to its thin construction,if not, spray intake cleaner around TBI while wiggling it, there is a rubber mounted TBI gasket that often fails in the 1.8l engines.
