1984 Jaguar XJS V12 Auxiliary Air Valve (AAV) rebuild

Removing and repairing the Auxiliary Air Valve (AAV) or Extra Air Valve in a 1984 Jaguar XJS. These valves are what controls the cars idle from high idle when cold to a slow idle when warm. When these valves go bad from age the cars idle will no longer be consistent. You can buy these new but are very expensive or you can purchase a rebuild kit from John_John1 on the
