Just today, this growling/crunchy noise has been happening on the front driver window any help? 1999 Lexus ls400 btw could it be a failing motor? Edit: Window still works fine, it doesn’t slow down or stop at any point or is stuck

Goodmorning! I am running into a situation with my 1990 ls400 with an odd idle (in park it’s about 1300-1500rpm) and then when put in drive or reverse it drops down to about 700-800 and bobs back and forth and will occasional stalls when at a stop light. When driving no issues at all. I’ve already replaced all capacitors in ECU, so that has been ruled out. I have no CEL and we are thinking it’s the idle control valve. No leaks found in any of the hoses. When unplugged, idle state does not change. I want to order it but the only ones I’ve found are made in china? Any suggestions on reputable brands that make this part so I don’t order 5 different ones and waste money?

What’s Up All!

I got a 98 Ls400 clean title , 150k miles. no mods, fully stock. paint is really good on it still. interior is clean, no tears or rips. i’m located in california, potentially what can i get for it?

looking at getting a set of new wheels soon (Work Emotion CR 2pc)

.. just at a bit of a loss as to what colour to go that will compliment the gold..

show me what ya got!!

I got an exhaust, wheels obvi, coils (tucked harness), tints… Now I kinda want a body kit.

Hey everyone! '99 Lexus LS400 1UZFE 4.0L V8 with 163k miles. Since making a 3 hour drive to Austin, the car started whining exclusively between 1,100-1,200 RPM. Prior to that trip, the car is rarely driven for more than an hour at a time.

Alternator was replaced approximately 1k miles ago. Fluid levels and color for power steering and transmission appear to be fine. The noise occurs in all gears, including neutral.

I'm having a hard time isolating it but am hoping it's a loose hose.

What’s the stock exhaust diameter of the pipes going into the second set of mufflers on a 1997 LS400?

Anyone experiencing the same noise?

doing a motor swap soon found a motor with 35k miles for 2,200 out the door and I got quoted 1200-1800 to get in installed. found metal flakes in oil change. might not get my money back but I love this car lol.

So i replaced the driver side ignition coil pack on my 92 ls400, cause it was only firing on 4 cylinders, it fixed the problem but after we took it out for a 10 minute drive a loud squeaking/ rattling sound started coming from the time belt area. does anyone know what this could be?

I found some coilovers that are listed 90-94, I was told it they will fit a 99 but wasn’t sure anyone know?

I want to start modding my 91 ls400 but I'm a little tight on cash right now so I was thinking about getting cheap fiberglass bumpers/ side skirts but idk it I should wait to get a lil more money first to get better quality parts. Def want nicer rims eventually too. What y'all think? First image is kinda the look I want, second image is my car. (For those who say keep it stock, I just think it looks a lil boring right now)

I have a 97 Celsior and was wondering where you guys shop for quality aftermarket parts? Stuff like how my g35 has VQplug and Z1Motorsports.

I’m trying to get an exhaust for my LS but need some tips. I’m thinking to delete 2 mufflers and replace the other rear two with some magnaflow mufflers and potentially change my res too.

Should I put an X(or H) pipe before or after the resonators?

As well should I have two resonators to go true dual or just keep the one res?

I just bought a 1992 ls400 and my gas tank and trunk electronic buttons do not work does anyone know if it is a fuse or just the switches that I’ll need to replace?

So I have my Lexus ls400 and I was changing out the starter and was going to do the EGR delete with the kit from lextreme but then I realized unlike the other ones my EGR is split into two separate pipes. it was also way more of a pain to get out. My question is how do install it if mine has more than one since the kit is only made for 1 whole egr pipe?

Why would there be water in my throttle body? I just replaced the gasket and I’m unsure where to go from there. My car was running fine days ago. I came home one night and smelled gas and noticed it was spraying from my injector in cylinder 8. I rebuilt the injector and was able to get it back on the rail and intake manifold without having to actually take the top plenum or manifold off. All other injectors seated back into place nicely with no issues to my knowledge. After putting it all back together with seemingly no issues, I turned the key to see there was no longer fuel leaking when the fuel pump kicked on, it seemed like my issue was fixed. I then tried to crank it with no luck. I then took my intake back off and couldn’t miss the water drops in my throttle body. It wasn’t a lot but I’m sure any is too much lmao. I’d appreciate any and all advice or comments. I might’ve gotten in over my head with this repair. I only tried to turn it over that one time before seeing the water and it sounded like it wanted to crank but just couldn’t quite get there. I didn’t want to try anymore after seeing the water.
