I went and had some work done on my 93 LS and the guy said " Your water pump is going out. I saw some moisture on it. You should be fine in the winter, but I would not let it go too long." I am new to the Lexus world, but I thought if a water pump was going out I would KNOW it (overheating, puddles, etc.) I have no puddles in my garage and my reservior level has not changed in 3 months. 1. How will I know when my water pump is going out? ALSO, Attached is a pic of my temp gauge. Is this a normal range for city driving? Seemed a bit hot to me. Thanks for the help, Duane

So I replaced my front brakes (not OEM) for the first time this past weekend and, while taking the worn right front off, I misplaced the clip for the sensor wire. I got an e-clip and put it back together and I thought everything was fine. BTW the previous owner cut the sensor wire on the left side. When I started the car, the brake sensor light came on..and stayed on. When I call the dewlership, they said that I need the clip, but they do not sell it. The question is? Do I need the clip? Is there another clip that will work? Where can I get one? D

Thanks for all the advice. I tend to forget that I own a Lexus and I should treat it as such. BTW, I went with the OEM and the problem is fixed.

I am being told by a "certified" Toyota/Lexus repair person currently working on my car that aftermarket coils do not work on my car because they do not have the proper resistance necessary for my LS400. I kinda know what that means and I think it is a load of crap. Is this true? Backstory- I had some shuddering going on when I taxed the engine- almost like backfiring- and made the determination that the coils neded to be replaced. Got to the top one, but the one under the distributor was too difficult for me, so I took it to a repair shop for them to replace it for me. NOw I am replacing both- plus some other crap. AND- he also said I should use an OEM oil filter not an after-market because of some kind of oil sensor that tells the engine iff the filter has oil in it or something. Should I be looking for smoke being blown up my !Removed!? D

Really good story. Just another reason validating my purchase. Glad everyone is all right. D

And when should I change it? D

And your motor is probably fine. Search the forum for antenna and you will find the fix.

I will wait 6 months or 5k miles and go synthetic. I like this forum.

I am about 1500 miles left for an oil change, but it has been 3 months. Should I go ahead and get it done? And I don't it has synthetic in it, but should I go to synthetic anyway? Is there a significant benefit to it? D

I can roll driver-back window down, but not up. I am using the driver controls and I can roll the back window on my side down, but not up. Passenger back is no problem. WTF? D

Added the OEM brakes to the rear and it was somewhat easy (had a friend with more knowledge helping.) So far so good. No squealing and they stop like a dream. I just saved about $200. NEXT PROJECT!!

I bought some OEMs from the dealer for $85, which was a pretty decent price. I will give an update after a couple of "stops." BTW, should I use that stop squeek spray on these? Does Lexus have an issue with that? D

The ECM (engine control module) is basically the car's computer that controls systems like fuel injection, idle speed control, emissions control, self diagnosis, etc. OK. Does a failing ECM give any warning signs? I am having an intermittent low idle issue and I wonder if that would be the cause...

Good point.

Newbie question. What is the ECM?

I have owned the car for about a month so I don't know if I am on OEM or not for any of it. But if I don't go OEM, go ceramic?

I am about to replace my rear brake pads and I don't know of I should replace them with OEM or go with non-OEM pads? I have not taken the calipers off yet so I don't know if the rotors need to be re-surfaced/replaced. I am just concerned with the pads right now. OEM or Non-OEM? D

I think #1200 is a bit much. Look here: http://www.lexls.com/ I thought about fixing/replacing mine myself and I think that is a a job too big for me.

I have a '93 and I am working on that very same issue. Here is the link that I am using for the part (when I get around to it) http://www.lexuspartsworld.com/Scripts/default.asp And think is the link on working on the antenna mast: http://www.lexls.com/ Hope that helps, D

I know. I have the same intermittent dilema. I will drive the car for 4-5 days with no problem, then it will happen once. I may try the throttle body fix and see how it works for me. D

I just spent the better part of 2 hours reading an older thread on here concerning an idling issue with 95's and I read that there were some older LS's with similar problems: 1. Car will idle in 500-600 range, then drop to 300-400, then go back up to normal. 2. Occasionally it will- when stopping- drop below 200RPM for a second, then back up to the normal range. 3. There have been times when the car has died on pulling away from the light. This has happened a couple of times. 4. This problem has only happened to me when I am stopped at a light or when the car has been running for a very short time after sitting for a few hours to overnight. 5. The problem is intermittent, although I feel the problem will get more frequent if not addressed. I read a couple of possible fixes: 1. Fuel filter 2. IAC?? Where is it? 3. ECU, but that has not been verified for older than '95 cars. I have this problem and I am searching to fix it, so I thought I would start this thread so that we can find a solution for the old LS's D

I just bought a 93 400 and I have pretty much the same problem. I used the directions above to "reset" the key I have and it did not work. I also replaced the battery in the key and it still ddi not work. Do I have to just reseat the ROM chip and try the process over? Are there pixs on the forum for that chip. I have read where it is located, but I don't want to pull the wrong thing. D

Im sure this has been addressed, but does someone has a link to the forum notes or can someone explain how to fix? Thanks. D

Hello everyone. I just picked up a 1993 LS400 with 150K. Everything I have read about these cars tells me that I can expect another 150k if I am mindful of the maintenance. I have only had it a week and I really like it. A good choice. D
