listed below on 1982 California "G" cars (including "G" wagons) with 3.8L V6 engines, when it has been determined that affected systems are within
specifications and functioning normally.
A.
Chuggle at 40-45 mph
B.
Tip-in hesitation
Before a decision is made to install both parts, vehicle should be roadtested for the owner described conditions. Unless all other areas are correct, the
PROM and EGR valve will not be effective for the purpose intended. Use the attached checklists for additional assistance if necessary.
A.
Condition: Chuggle also referred to as surge, is most noticeable at 40-45 mph and should not be confused with "Freeway Hop", a common
condition in many areas. Converter clutch engage speed is increased to 50 mph from 41 mph.
B.
Condition: Tip-in Hesitation may be experienced during either hot or cold operation while going through a light or moderate acceleration period
from a stationary vehicle position.
If any one or combination of conditions exist, install both parts, PROM and EGR valve.
