A quick way to isolate a leak like that would be to locate the vacuum port remove the line or lines, cap the port and see if that changes your idle problem. Leave the vacuum line connected for the distributor advance. Your vacuum advance I would look there also.
67 Caprice, not sure but if it has vacuum controls for the AC & heat that could be a dicy little problem. Capping the vacuum port after removing the vacuum lines, except for the advance would isolate all of that also.Last edited by pepi; 06-05-2012 at 07:48 PM.
