Throttle Difficult to Open on Cold Engine
- Normally Aspirated Engines -
Modify Crankcase Breather System
ISSUE:
On some 4.0L XJS vehicles, owners may experience slight difficulty in opening the throttle from the closed position after the vehicle has been sitting for some time. Under certain circumstances, oil mist from the crankcase may collect and harden on the throttle body and plate when the engine is cold, where it may cause this condition.
ACTION:
Perform the following modification to include an oil separator in the crankcase ventilation system, along with cleaning operations on the throttle body unit, only when there is a history of customer complaint of the condition described above.
