ISSUE:
On some 4.0L NA Sedan Range 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.
