SOURCE: 1991 LS 400 Lexus has water leak at sun roof. How

each corner will have drains, sometimes you can get a long air gun and shoot some air down there and clear the stoppage, but be careful that you dont blow the hose off. sometimes it just may need to be lubricated.

SOURCE: my 1992 lexus ls 400 keeps stalling and idleis very low

Look for a small electric motor near the accelerator cable and near the top of the valve cover.

It's call IDLE AIR CONTROL (IAC) motor.

It's job is to increase the idle when load is added.
Example: turning on headlight,turning on AC.

Testing it is simple.

Warm up you car for 10 minutes.

Locate the IAC motor

turn on loads.....AC,headlights,etc


The motor should move the idle up


If the motor does not increase the RPM then it can be stick.

Try to give it few gentle taps to free up the gears.

It can be clean if your are up to it.


This electrical motor is very expensive. Please handle it with care.

====

The other trouble spot are

old accelerator cable

TPS Throttle position sensor

====

I will do a simple tune up and gas treatment before starting to replace any parts.


Please post reply on the comment window.
