Whoever has a problem with their Lesabre dying at corners and bucking on hiway, try adding a ground wire anywhere from engine to frame. I added a solid copper piece from a bolt i think holds starter or flywheel cover on to bolt that holds a metal shield forward of A/C area on front crossmember. Be sure connections are good and clean. Eng hasn't died since, and seems to not buck as much, but still a bit. It is a '91 Limited, 186K miles. A piece of baling wire probably just as good. If anyone tries this, would like to know if it helped you. Thanks, Huey
