Hi guys, first time having a lexus. We'll i just bought a 93, with 119k miles. has all maint. records from the lexus dealer, pretty much in perfect cosmetic condition and no accidents. After my second day of driving, ive been noticing problems.

#1, misfiring, idle stumblings, power loss, acceleration hesitation thoughout rpm *fixed problem* bad sparkplug wire. also replaced sparkpluges

#2, slight hesitation when acceleration from dead stop. feels like power stops, then immediatly starts again, low rpm range. hesitation is the best description i can think of, but its real slight and starting to get annoying.

#3, my speedo needle glows half only, and when i turn my car keys to the acces. position (not starting car but turnon on electricals) my HUD lights do not come on at all, not even when i turn on headlights. it does this even when i start the car. when i leave it alone for a while, it starts working again, but if i ever turn the key to the on position without starting the engine, it will do this.

#4, my nakamichi stereo just lost sound. completely. its on and i can change radio stations and such, but no sound.

#5, my powersteering sucks when im parallel parking or comming out of parallel parking. but when im driving it feels perfect.

#6, my window switches arent working right..works every so often, doenst seem like the motor is dying, just maybe a bad switch? anyone else have this problem?

#7, just a question, i plan on replacing my shocks with kyb gr-2's and just wondering if my elec. height adjustment and damning will stop working?

Thanks in advance for any help you guys give me, sorry if i didnt search enough..

You should've changed caps (2) and rotors (2) along with the spark plugs and wires.
Needles going out is a common problem.
Did you get a car wash recently? Could be water leaking through the trunk and onto the amp, or a bad amp.
You need to be more specific...elaborate on what you mean by "sucks."
Could be the switch, but it could also be dying motors as well.

If you have air suspension, then you can't replace it with KYB's...you'll have to replace it with an air suspension shock (around $1000 new) or convert your entire suspension to springs/shocks.

actually a mechanic did this for me, but he didnt say anything about cap and rotors. any idea on how much for the parts and how hard of an install?

actually just got a car wash today. guess thats that.

the power steering is hard to steer while the car isnt moving. multiple turns on the steering wheel...while parallel parking. it gets hard...actually kinda feels like the power steering pump is trying...but once im going, even making turns at lights its fine.

BTW, thanks for the help.

Hope you didnt pay too much because you sound like you bought a money pit.

ls400newb

i paid 4700. and im kind of bummed out cus iv'e already spent over $300 for the spark plug wire set w/sparkplugs installed. :[

Actually you just seem to have all of the common problems associated with first gen LS's.

Maybe a throttle body cleaning or seafoam treatment just to see. Have you checked the air filter?

ls400newb

actually, i love the car. its just these small problems that nickel and dime you broke. im going to use that seafoam stuff today and see how that feels.

Rotors were $9 each and caps were $19 each from Carson Toyota (www.l-tunedparts.com).

The carwash explains the loss of sound. Just give it a day or two for the water/moisture to dry up...leaving your trunk open in the sun will speed up the process.

Did you check the power steering fluid level? Maybe it's time to for a PS flush/clean?

actually, the radio is ok now.

as for the PS, i will check the fluid level, and possibly do the PS flush.

i used to own 5 nissan silvias (turbo) and we used to put ATF tranny oil into the powersteering instead of PS fluid. everyone in the Nissan community knew about this fix. Worked MUCH better and fixed all leaking/ps problems. Wonder if the lexus PS works the same way.

This car is supposed to use Dexron III ATF fluid in the power steering system. Not the bottles labeled "power steering".. Make sure you are using Dexron III, and check the power steering sticky thread at the top of the forum for more info.
