1999 Toyota 4 Runner

VEHICLE STALLS/QUITS WHEN BRAKING, USUALLY BETWEEN 0 AND 10 MPH. STARTED AFTER HAVING VEHICLE FOR 2 WEEKS. DEALER FIRST VISIT, THEY COULD FIND NO PROBLEMS. SECOND VISIT, CHANGED THROTTLE BODY, DID NOT SOLVE PROBLEM. SAID IT WAS PART OF A GROUP THAT NEEDS NEW COMPUTER, THAT DID NOT HELP EITHER, SAID IT MAY BE THE TRANSMISSION. PROBLEM STILL NOT SOLVED. TOYOTA TECH LINE TOLD THE LOCAL DEALER IT MUST BE A FLUKE JUST GIVE IT BACK TO THE CUSTOMER (ME). I GIVE A LOT OF CREDIT TO THE LOCAL DEALER SERVICE PERSONNEL, THEY TOLD ME THIS AND TOLD ME IT WAS UNSAFE TO DRIVE. THEY ARE WORKING THE PROBLEM AND GAVE ME A LOANER CAR. PROBLEM IS GETTING WORSE, AT FIRST IT WAS OCCASIONALLY, BUT NOW IT IS STILL INTERMITENT, BUT WILL OCCUR NUMEROUS TIMES A DAY, IF YOU DRIVE IT. *AK
