Crankcase Ventilation (PCV) Problems
Often reported
The crankcase ventilation system (PCV valve, oil/air separator, and hoses) is a frequent source of trouble: noisy PCV valve, cracked or dislodged brittle hoses, and clogged separators. These faults can cause vacuum or pressure leaks.
Engine Bay
Misfires and Ignition/Injection Faults
Often reported
Misfires, rough running, and power loss are reported. These are attributed to ignition coils, spark plugs, and sometimes injectors or carbon buildup on valves (typical for direct injection engines). Replacing coils or plugs usually resolves the issue.
