Air Induction System Precautions

AIR INDUCTION SYSTEM
1. Separation of the engine oil level gauge, oil filler cap, Positive Crankcase Ventilation (PCV) hose, etc. may cause the engine to run out of tune.
2. Disconnection, looseness or cracks in the parts of the induction system between the throttle body and cylinder head will allow air suction and cause the engine to run out of tune.
