1995 993 vacuum leak , intake center valve

Fuel System

Vehicle Information: Model: 993; Year: 1995; Body Type: Coupe; Total Mileage: 132000;

Thanks to your website I am slowly becoming very alert and good at maintaining my beloved 993. After reading one of your expert answers pertaining to the ISV I discussed it with independent (993 race car driver) mechanic. After taking my car in at least 4 times he could not duplicate the RPM''s surging and the engine cutting out at frequent stops,so I decided to take my love to the "DEALER",the dealer stated the ISV had to be replaced, after replacing the ISV,on the third day of having my car,I was told that I had vacuum leak in the intake center valve. My car has been running great other than the ISV problem. I know this is going to cost big money,please tell me what this repair entails and the cost. Thank you.
