MY CHEVY IMPALS LS 2000 HAS BEEN STALLING WHILE HOT ON THE PARKWAY. THIS IS A SERIOUS SITUATION. THIS WAS HAPPENING INTERMINTELY ABOUT EVERY FEW MONTHS, THEN RECENTLY IT HAS BECOME A DAILY EVENT. MAYBE 1 - 6 TIMES A DAY WHILE ON MY WAY TO WORK. THE DRIVE IS ABOUT 30 MILES, ONE WAY, AND IT STALLS USUALLY TOWARD THE END OF THE TRIP. I HAD THE THRODLE BODY REPLACED LAST WEDNESDAY AT THE DEALER, AND IT DID NOT FIX THE PROBLEM. BEFORE THAT THE GAS FILTER WAS REPLACED. THIS WEEKEND IT HAPPENED FOUR TIME ON SATURDAY AND FOUR TIMES ON SUNDAY. THIS IS A VERY DANGERIOUS SITUATION ESPECIALLY ON THE PARKWAY. I HAVE HAD IT TO THE DEALER A NUMBER OF TIMES AND THEY CANNOT IDENTIFY THE PROBLEM. AFTER THESE STALLS OTHER CARS ARE ALMOST RUNNING ME OFF THE ROAD. I HAVE BEEN LUCKY. I LOVE THE CAR AND DON'T WANT TO GET RID OF IT, BUT IF THIS KEEPS UP I MAY HAVE TO.*AK
