Will a power steering pump off a 98 lexus es300 work for a 98 lexus ls400?

If your is exhibiting the same signs as a dead battery it really sounds like your alternator is bad. If you are handy, you can remove the alternator and take it to an autoparts store like autozone and they will test it for you. This is not a hard job to do, usually 2 electrical connections, 3-5 mounting bolts and you have to pop the belt off. Just reverse it to install a new one. Good luck! - Nick

There is a loud squeak on the front of my 1991 ls 400. The squeak is near the alternator. Any one no what it is?

I looked it up on AutoZone.com and it looks like there is only one coil.  You can verify that by giving them a call.  However, to me it sounds like you might be having a problem with your idle air control valve.  Since you are only having problems when the vehicle is at idle I would take a look at your IAC.  It is located on the throttle body and is usually held on by two screws.  When the IAC starts to go bad you will have problems with the vehicle when idling.  Let me know if you have any other questions.  Thanks for rating my response and for using FixYa!

I also have the same problem, I would also be happy with a diagram of the location of the sensor.
