The above vehicles built before September 8, 1983 may exhibit an erratic carb idle and/or detonation on acceleration. This symptom may be caused by
an oversized female terminal in one of the three positions in the Throttle Position Sensor (TSP). This condition can prevent the EEC module from
receiving the signal from the Throttle Position Sensor.
If the vehicle has the above customer concern check the Throttle Position Sensor connector by the following procedure:
1.
Remove the wiring connector from the Throttle Position Sensor.
