PROCEDURE
VISUALLY INSPECT HOSES, CONNECTIONS AND GASKETS
Visually check that the hoses, connections and gaskets have no cracks, leaks or damage.
Note
Detachment or other problems with the engine oil dipstick, filler cap, ventilation hose or other components may cause the engine to run improperly.
Air suction caused by disconnections, looseness or cracks in any part of the air induction system between the throttle body and cylinder head will cause engine failure or engine malfunctions.
If any defects are found, replace parts as necessary.
