Exact same problem on my '90 LS400. Local machanic says replace starter motor is only option as it's a 4 hour job to get out, so you want to be sure it's fixed. However, as you have the exact same problem (and mine is only from cold also), if one of use were sure what the problem was, would it be worth trying to fix the motor? My guess is that it is just a lubrication issue. If it were half-an-hour to get it off, it could be fixed by now! Having just spent a massive amount on suspension bushes, I'm a bit committed to sorting this! Just noticed your post is a year ago.... Did you fix it? Dave/.

My '90 is the same, when cold tick-over is around 1500 but it goes into gear quite smoothly! My problem is that as the engine warms-up tickover does not drop until I stop for about 20 secs. If I drive off from cold, and drive for hours without stopping, tickover is still at 1500 at the end of the journy. Even nocking it into neutral while moving does not drop the tickover, I must actually reduce road speed to 0mph! I think that there may be a computer that known somthing about this! Any thaughts on this problem would be appreciated. Dave/.

Have "Exactly" the same problem on '90 LX400 with 160k. After a couple of minutes. driving, the same speed bump, at the same speed is completely silent! I will be investigating when I feel a bit more like crawling under the front end. Will post any solutions. Dave/.

Having just acquired a '90 LS400 I need to attend to a couple of problems to make it "perfect" One that is causing some thought as to how to rectify a problem with the inner trim of the rear doors. The facing material has "delaminated" from the backing at the top of the door card (where it turns to meet the chrome strip at the bottom of the window glass). The previous owner has obviously tried to glue this back but it was not successful. I'm not sure what type of glue was tried, but it would need to be pretty good! I can't believe that his problem is unique to my vehicle, and not wanting to "re-invent the wheel", has anyone come across, and more interestingly, solved this problem. Any thoughts would be welcome.
