Does anyone know what the two thermo vacuum valves that are located by the idle air control unit on the top front of the engine do? I broke both of them cleaning in the area, they were super brittle I guess. Car seems to operate fine even though they are broken leaving open vacuum lines? I'll of course be looking for new ones. Performance had them for about $20.00 each. Does anyone know if that's a good price on these? Thanks Oh Yeah its an 86 560SL.
