Hi guys, I've been experiencing near identical symptoms except the vehicle isn't throwing any codes... I spent a couple weeks going over everything and going through possible causes over a process of elimination with no luck.. Mechanics had the car for a week also with no luck diagnosing it.. but came to the conclusion it was the cat being 80% blocked. I've since done a cat-delete (welded in a piece of pipe) with no luck. any help appreciated

Hi there I'm from down under in Australia. I own two LS400s a series 2 1995 model, and a series 1 1992. We go off Kilometres and not Miles over here but I thought I might add on this page.... my series 2 Ls has just clocked over 1,100,000 klms on the odometer!! equivalent to 800,000Miles! and might I also add... it has a full genuine Original purchased from Lexus dealership service history!! not one service has been missed by the lexus guys for its whole life ! it still drives like it would of the day it left the showroom floor. original engine, never had a head gasket or anything done !!
