2ltr turbo idle problem

[Big Dean t]

Alright guys I need some advice, I've got a turbo scooby and it's not idling right, if you blip the throttle the revs go up fine but when coming back down it bounces and nearly stalls and sometimes stalls. If it doesn't stall it'll bounce for a few seconds then catch it and smoothly idle..

I've changed the plugs, cleaned the throttle unit and changed the maff sensor, still nothing..

Any advice would be appreciated

Thanks!

Is there an idle control valve on these? Not overly familiar with these particular lumps yet but sounds like a typical idle control valve issue
