I have a 96 LS 400 that occationally stalls (idle is very low and then it drops out) when I stop after a long drive. I can immediately restart the engine without a problem and the idle returns to normal.
The problem was first noticed after 50,000 miles but it was infrequent and the dealer didn't know what was wrong. Now the car has 130,000 miles and the problem is more pronounced (still only after a long drives) and the dealer still claims not to know what the cause is.
This sounds exaclty like your description. Could you please give me some additional information so I can inform the dealer and get them to fix it or fix it myself.
Thanks
