  1. I'm looking for the 1997 LS400 Repair manual. I realize that they are probably similar across model years but since I don't know the differences between them, so I am looking for the 97 manual pecifically. I have the "Electrical Wiring Manual" but can't spend $400.00 for a danged repair manual. Anyone have one they want to unload? Thanks. Paul
  2. Sweet ride. I bought mine earlier this year with 234,000 miles and it was still a steal. I love my car. My GF named her "Lady Pearl." Changed the Timing Belt, had paint correction done, repaired an outer tie rod and not much more. If you decide to keep it, it should serve you well. Paul
  3. While doing an inspection of my 97 LS400, I found one of two hoses to the "Power Steering Air Control Valve" (located below the power steering pump, passenger side) disconnected. The other hose was still connected but neither hose had a clamp so they could have been correctly or incorrectly installed in the past. Investigating the air control valve component, I determined that there should be a connection on one of the two valve nipples to the Air Intake Hose just after the MAF, and one that goes to the upper Intake Manifold. From the pictures I can find of the valves operation, and research I have done, it shows air flows through the valve to affect the engine RPM while turning the wheels to their maximum. (I don't believe it because the vacuum created by these two air supply points on valve would only open to allow more power steering fluid to flow through. More differential pressure (higher RPM's), the more the valve opens. But hey, what do I know.) What I cannot determine is which nipple is the one that connects to the air intake hose and the one that goes to the intake. One nipple has a tab. One does not. Does anyone know if the tab is the inlet side? Thanks.
  4. There are no user serviceable parts on the speedo. The Lexus instrument cluster boggles my mind at how beautifully complex it is. An engineering work of art is the best way I can put it. As long as everything else is working (i.e. trip meter, odometer and cruise control, lighting) you can be certain that the speedo itself is at fault. The only way to repair it is to either replace the speedo assembly itself (which is not too terribly difficult "or" replace the gauge cluster. The same goes for any of the actual gauges. I am an electronics tech of 35 years. It's not difficult to pull the cluster, get the P/N off of it and find one on ebay to replace the gauges. Just swap the "top" board with all of the coils of wire and other components to move your original/true mileage (stored on one of the chips) over to the new cluster. Takes less than an hour to do the whole thing. You need a phillip's screwdriver and a thin blade flat is helpful. There are if I remember correctly, three ribbon cables at the top to switch over and three other normal type of connectors on the bottom. That's about it. I had the same issue. Did what I am recommending. worked fine. No more speedo issues. Easy squeazy. Just a little costly to buy a used cluster. Good luck.
