NHTSA Complaint #10434042 — 2004 CHRYSLER PACIFICA

1ST TIME: DRIVING STRAIGHT AROUND 20-45 MPH WHEN ENGINE LIGHT CAME ON & ENGINE STARTED ACTING UP. STOPPED SHORTLY AT A STOP LIGHT & ENGINE DIED. HAD TO WAIT SEVERAL MINUTES BEFORE THE ENGINE WOULD START & ENGINE LIGHT STAYED ON UNTIL WE GOT TO AUTO MECHANIC'S SHOP APPROX 2 MILES AWAY. MULTIPLE TIMES IN THE LAST 2 MONTHS: SOMETIMES ENGINE LIGHT COMES ON AS WE ARE STOPPING OR DECELERATING OR TURNING LEFT AFTER A STOP LIGHT CHANGES. ENGINE THEN ACTS UP & SUBSEQUENTLY DIES SHORTLY AFTER THAT. AFTER A FEW MINUTES WE ARE ABLE TO START IT & DRIVE IT HOME OR TO THE DEALER. BOTH THE AUTO MECHANIC'S & AT THE CHRYSLER DEALER'S DIAGNOSTIC MACHINES IDENTIFIED FAULT CODE "P0508 IAC CIRCUIT LOW" & TOLD US WE HAD TO CHANGE OUT THE IDLE CONTROL MOTOR (CHRYSLER PART # 4593851-AA). WE HAVE HAD THIS PART CHANGED OUT & THE THROTTLE BODY CLEANED TWICE NOW WITH NO RESOLUTION OF THE PROBLEM. WE ALSO HAVE NOTICED ON OCCASION WHEN WE HAVE OUR FOOT ON THE BRAKE AT A STOP, THE ENGINE MAY ARBITRARILY RACE FOR A COUPLE OF SECONDS. FORTUNATELY OUR FOOT IS ON THE BRAKE WHEN THIS HAPPENS. *TR
