Cruise control will disengage intermittently.
Engine cuts out when vehicle comes to a stop.
Beginning with the production date of May 1987, the Hall-effect sensor, which is mounted on the speedometer, may have a defective cold solder joint on the sensor output pin. Your 1988 vehicle cuts out when you come to a stop but will restart immediately. Gently wiggle the output pin. If any movement is detected, the sensor is defective and should be replaced.
