ISSUE: White smoke from the exhaust at engine idle after extended highway driving or spark knock at about 65 MPH (104 km/H) with a load on the vehicle may be caused by the strategy of the EEC IV processor. In addition, a no start or a hard start condition after a (overnight) long soak in ambient temperatures around 70 degrees F (21 degrees C) may develop.

ACTION: Install a new level EEC IV processor with revised operating strategy. Refer to the following procedure for service details.

1. Perform EEC IV Quick Test. Correct service code(s) as necessary.

2. Remove the existing EEC IV processor.

3. Install a new level EEC IV processor (E9TZ-12A650-ADA).
