Cruise control

Does the cruise control have a vacuum line attached to it? I have a rough idle and that is the only thing I can think of. It looks like it should have a vacuum hose attached but I dont know.

yup, there are also 2 vac hoses that go through the firewall to the HVAC, and a mess of them on and arouns the vac canister

Do you have a picture of where the vacuum line comes from or schematic? I have been searching for a vacuum leak for a few months and can't find it.

get a propane torch, do not light it but turn the gas on just a little, hook a hose to it and trace your manifold, start pulling and plugging lines at the manifold to find out of they are downstream of the manifold
