Hey Monarch. I'm new to the world of Lexus. 1992 LS400 271K running like a champ. Just wanted to make friends with the Gurus on the site. Thanks

And after looking over a few forums it does say to use Dextron II / III ATF. Now with that said am I looking at any power steering failure? Should I flush the system? I've had the car since Nov 2010 with no issues. I am going to replace the air control valve on the side of the pump just to make sure that the valve is not leaking into the engine. Any feed back will be helpful. Thanks.

I've been having power steering problems. Had blue smoke at a cold start up. Replaced to vacuum hoses from the Air control Valve. Did not replace with the original hose(aftermarket vacuum hose) Now I hear an suction sound from the power steering unit, but no low idle. I did make one mistake adding regular power steering fluid to the unit. I did not know that the unit requires Dextron II ...

Ok I need a little help!!! I recently had a bad Idle Air Control Valve. Replaced that. But now when I start the car in the morning I have to give it a little gas in order for it to keep running. Car will run on it's own after a few seconds but with a low idle. Checked all the vacuum lines but I seem to still here air around the power steering pump area. Any help please..

Love My LS 400

Finally got my first Lexus up and running. This car runs like a champ. I have a 1992 LS 400 with 268K. When I purchased the car it needed rear brakes/idler pulley/battery/oil change/fuel filter. Now she is up to speed. All of the problems that I had before, I solved them by cleaning the throttle body and replacing the fuel filter.
