SYMPTOM/CONDITION
^
Part Throttle Loss of Power (Sag) - Engine will intermittently loose power (sag) suddenly while driving at a constant road speed, usually at
highway speed, but could also occur in city traffic.
This condition is usually characterized by having a good idle and has wide open throttle, but is substantially weaker because it still lacks primary
venturi fuel supply when the loss of part throttle power occurs.
^
Cold Drive Sag - This condition occurs normally on a medium or heavy acceleration which allows actuation of the carburetor secondary.
^
Vehicle may exhibit a warm surge.
DIAGNOSIS
Because of the difficulty in duplicating these conditions in the shop or on a road test, the repairs for each are being released as a package and should be
installed as such.
