If you can't find your answer to the 1994 LS400 I have owned the Lexus LS400 that car in Japan is also known as a Toyota celsior so if you were to look up information regarding the Toyota celsior the year of 1994 you can find a column gear answer to your question

They may fix, but keep in mind that 1994 is non -VVTI and the 1999 is VVTI. (They would have different specs.) Therefore different timing, GL.

I have a 97 Lexus ls400 I replace the catalytic converters the fuel injection rail system injectorsCadillac converter still turning red need help

I have the same problem - did you find a solution yetI bought a used on ls400 ECU from a junk yard but it eeds to be "RESET" how do I do that?

main Compter is bad underneath the dash board repair it it can be fixed

Check the wiring harness in the left trunk hinge. You need to check for broken wires, most likely the yellow and wht/blk wire. Its a common problem with this model....Good luck.

Could be a motor mount.

you will have to replace the complete speed/tack
asy. they are know for going out. very common.try internet for good deals on reman units.
