BoyBlu70 Posted August 12, 2005 Share Posted August 12, 2005 When I start my 1990 LS400 it runs but will not idle at all prior to this happening I notice that it had a low idle at about 100 to 200 rpm and when I was coming home one day I stopped at a stop light and the idle dropped and then the car started cutting off, anyone got a clue the tps has been replaced and the Idle positioning sensor was to and still no idle.
