slide the lower part of shifter handle down and you will find two screws, but there is 2 wires coming in from center console for overdrive button.you have to remove the center console cover and remove the 2 wires from connector and then pull up threw handle.when you go back together you will have to guide them back threw the handle.

SOURCE: 1993 Lexus Ls400 loss of power at 2500-3000rpm

Check your MAF and MAP sensor. The first 80% of your throttle signal from the TPS works with the O2 sensor to try to keep the air fuel ratio to 14.7 to 1 with the ECM controlling the fuel injector spray time and timing the ignition. After the 80% to WOT the ECM puts the O2 sensor in to an open loop and takes the Reading form the MAF and MAP sensor to run the engine richer so there will not be any Detonation to the engine and burning holes in the valves for running too lean. That is why it always feel like you get a little more when you ease off on the gas peddle from WOT. Recap check the TPS, MAF,and MAP sensor and wires to those sensors, if you can get the car scanned that would be great and you may find out which sensor may have gone bad, the other thing to is the fuel pressure regulator may be going bad and at WOT the pressure may be to high causing it to run to rich causing the loss of power. Good luck and hope this helps.

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.

Not too bad. Not much room, just enough to drop the starter. It is probably easier to go up through exhaust if you can get your exhaust shield off the manifold .

1990 lexus ls 400 security system went off now vehicle will not start. Keys open door turn alarm off but starter will not engage. What can I do?


Your alarm is keep your system from starting. When the alarm system fails, you have 1 of two choices, if it is a after market alarm then just disconnect the alarm, if it is a manufacture alarm then you will need to take it to a company to have then replace the alarm or disconnect it. Doing so yourself you can hurt your vehicle more then help it
