Air Injection Hose/Tube: Testing and Inspection
Air Management Valve
Check around the air manifold for air leakage with the engine running at 2000 rpm. If air is leaking from the nozzle sleeve nuts, tighten them.
Check and replace hoses if found to be fatigued or cracked. Also check hose joints and clamps. Be sure hoses are not rubbing against adjacent
components.
