I have a 1999 Cadillac Seville STS. For a while now the car will be running fine and then when I come to a stop sign or stop light, the car will stall. Usually at a stop light, but only after the car has sat there for 10-45 sec. and then when the light goes green right before i hit the accurate the car dies. This does not all ways happen, probably 10 percent fo the time, which is still a lot. The car doesn’t have to be cold or hot, it happens on short and long trips. It has been in to the shop to get looked at and no one can seem to figure it out. I used to believe that it occurred more in the winter because of the electrical load of the heated seats, and heater, but even when all the accessories are turned off, it will still stall. If anyone has any idea, or can even let me know that this has happened to them as well, that would be greatly appreciated.
Thank you.
