Vehicle speed control
CURSE CONTROL OCCASIONALLY MAKES ENGINE ACCELERATE WHILE AND AFTER BRAKE APPLIED WHILE MOVING UNDER 5 MPH AND EVEN WHILE STOPPED WITH BRAKE STILL APPLIED. MORE THAN ONCE A PEDESTRIAN WAS AT RISK IN A CROSSWALK WHILE VEHICLE STOPPED WITH BRAKE STILL APPLIED, THEN ENGINE SUDDENLY BECAME NEAR FULL THROTTLE, REQUIRING EVEN STRONGER PRESSING OF BRAKE PEDDLE. WE TOOK THE CAR TO DEALER (HENRY DAY FORD) WHO UPDATED ENGINE CONTROL ROM; BUT SAME PROBLEM CONTINUED TO EXIST. THE DEALER OFFERED NO WARRANTY OF REPAIR OR EVEN ACKNOWLEDGEMENT OF PROBLEM. WE NOW DRIVE WITH THE CRUSE CONTROL AND HORN AND ??? CABLE DISCONNECTED NEAR WINDSHIELD WASHER RESERVOIR.
