Vacuum Solenoids


Mounted atop the valve cover to the rear of the engine is a bracket with three gizmos and a bunch of vacuum hoses. These are vacuum solenoids, controlled electrically by the computer. The first two on the left control the upstream and downstream Pulse Air tubes. The one closest to the air cleaner controls the vacuum-operated portion of the Sol-Vac idle speed control on the carburetor.
