Rev's stay artificially high when off throttle?

[Robracer]

Hi guy's..

My 97' golf gti 8v hunts in low gear's, but i'm thinking the cause of that is when i come off throttle in the lower gear's, the rev's stay about 1,500 rpm for a few seconds then drop to 1,000 rpm. I've totally rebuilt the engine roughly a 100 miles ago, it runs sweet, pull's fine. No Vag Com codes what so ever, the dizzy is also set within the correct values.

Got any idea's?

Thanks in advance. Rob

air/vacuum leak ?

That would be a simple fix? I'll have a look when i get the chance.
