Abnormal Operation During "Accel" or "Coast"

In 1986-88 models, the vehicle may exhibit hesitation while using the COAST mode, or hesitation and dropout while using the ACCEL mode. This abnormal operation is caused by poor contact between the speed control brushes and the slip rings on the steering wheel. This poor contact is due to a buildup of contamination of the lubricating grease. The condition occurs more frequently when the temperature is hot and on vehicles with high mileage.

Correct the concern by removing the steering wheel and thoroughly cleaning the grease from the brushes and slip rings. Regrease using grease (E8AZ-19590-A). This new grease has been used in production since the beginning of the 1989 Model Year. Its use has resulted in a 90% reduction in the incidence of this concern.
