OK, It's not the cable and a return spring doesn't help. I've cleaned the IAC and throttle body. Any other ideas would be appreciated.
Thanks.

Hi Heep a Lot. Thanks for the advice. Can you explain a little more on what you mean to find the vacuum leak? Sorry I don't understand the process.
Cheers.

basically u start the vechile take a can of intake cleaner or soemthign that will bog down the motor spray all vacum hose connections , lower intake manifold, anywhere untill u get a reaction from the engine then constentrate on that area for abit untill u find the leak most likely a bad rubber hose some where
