You either have a bad engine coolant temp sensor & connector.Located under upper radiator hose at cylinder head Yellow & black wire.Original sensor is ceramic & replacement will be brass from saturn.Also you may check for vacuum leaks at PCV hose & valve.Hope this helps

SOURCE: 1993 Lexus LS400 acceleration stalls or surges

I HAD THE SAME PROBLEM WITH MY CAR. 93 LS 400. THAT WOULD BE YOUR FUEL FILTER OR THE FUEL PUMP GOING BAD. TRY CHANGING THE FILTER FIRST. THE DEALER TRIED TO CHARGE ME $980 TO CHANGE FUEL PUMP.

Sounds like you need to check your vaccum lines for a leak. This is easy to do. Buy a can on carburator cleaner and with a friends help keep the car running as you spray your vaccum lines with the carburator cleaner one by one. If you have a leak it will **** the cleaner into the lines and cause the vehicle to stall out. Replace the line if this happens and continue checking all lines until all bad lines are replaced.

When accelerating the car very fast it hesitates and then jumps forward hard and then shift to the next gear. Could this be the computer.


Its not going to be smooth accelerating under full throttle. but one thing to try is disconnect the battery for ten minutes, that resets the ecms memory. but then the car will lose the zero point calibration and youll have to take it to the dealer to have it reset, which doesnt cost anything but still you would have to go. or you could just go to the dealer and have them reset your ecm for you. they wont charge you for that either.

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.

Removing an automatic gear shift out of a sc400


position the shifter into the drive position, pull down on the plastic trim directly underneath the leather portion of the shifter. theres two phillips head screws behind that. remove the shifter knob and the plastic piece. the trim will pop out if you pull directly upwards, disconnect the heated seats(if you have them) and the trac button. hope that helps.
