well i have been having an overheating problem like many other ls owners and this morning i had a rough idle and then it would die. well i had it towed to the dealership. they will have my car for a week and they are replacing a/c compressor and pulley along with 3 wiring harnesses and the computer. also they will be replacing all the vaccum lines. well now all there is to do is wait. just thought id share a pleasent dealership expeirience with you. i went in there for one thing and they noticed other problems and they are fixing them under warranty while its there instead of future problems and future co-pay.
