UNPREDICTABLE PROBLEM. OCCASIONALLY, 5 TO 15 SECONDS AFTER I FIRST START MY 1999 MUSTANG GT, THE ENGINE WILL RAPIDLY INCREASE IN RPM AND THEN RETURN TO NORMAL. IF THE CAR IS IN DRIVE OR REVERSE AND I DO NOT HAVE MY FOOT FIRMLY ON THE BRAKE, THE CAR WILL JUMP FORWARD OR BACKWARD. I NOTICE THE PROBLEM MOSTLY WHEN I FIRST PUT THE CAR IN REVERSE. IT MAY HAPPEN 3 OR 4 TIMES IN ONE MONTH AND MAY NOT HAPPEN AGAIN FOR 2 OR 3 MONTHS. IF YOU DO NOT HAVE THE BRAKE APPLIED FIRMLY, I THINK THE CAR COULD EASILY JUMP 5 FEET BEFORE GETTING A FOOT ON THE BRAKE…
