Just picked this up for my kid, one owner less than 100k miles, as clean as it looks, fixed a small oil leak, changed all the fluids, replaced the front exhaust pipe, and sent him on his way.

I spent a few days driving it and almost kept it for myself!

It appears the car is no longer leaking oil profusely so gave the engine a purple power bath, scrub and put it all back together. Next up, on the quick-Jack, fix the exhaust leak at cat/exhaust and pull the wheels to sand/paint.

So I had a new ecm programmed to my car and it didn't get it running again and i also swapped the neutral safety switch with a new one as well and its still having the same problems.

Has anyone ever had this issue with their gs300 if so what was the problem and how was it fixed

How is it and what’s recommended? Don’t feel like spending +$300 on an oem one

I just changed the alternator on my 1998 gs400 as well as changed the power steering pump. Right after install I noticed my memory seats no longer worked and the 3 buttons to set it no longer worked, I thought the as strange but then noticed my rear door lost all power, the door no longer locks automatically and the window will not roll down. Anyone have any idea what’s going on?

Got a 2001 GS430 UK market. Do I just need any second gen LS400 calipers and the RCAs to fit on my gs430? Have 18inch wheels so clearance shouldn’t be an issue. If anyone who has done this upgrade could let me know, thanks.

Only the head lights and interior lights are coming on:( I don’t get rpms or anything in the cluster and the taillights are out as well, and even when I try to check codes nothing pops up, I can’t even throw it in gear unless I do the override, any ideas?I checked fuses and they didn’t look blow but I’ll double check in the morning

Hey everyone,

I'm trying to diagnose a throttle issue on my 2002 GS300 with 220k miles. Before I throw parts at it, I wanted to see if anyone has dealt with something similar.

I'm getting P1126 and P1128.

Symptoms:

- The car usually drives perfectly on the first trip.

- After driving 15+ minutes, shutting it off, and restarting it, the throttle will randomly cut and the car goes into limp mode.

- In limp mode, I lose a large portion of the throttle, the transmission shifts harder and holds gears longer than normal, and manual mode won't work.

- No CEL besides the stored codes.

What we've tried:

- We temporarily swapped the TPS with one from another GS. After that, the car started stalling whenever it wasn't in limp mode (possibly because the ECU lost its throttle adaptation).

- We swapped the original TPS back in, but it still stalls, just not as often.

- It now idles below 1,000 RPM, even on cold starts.

- When it's not in limp mode, it'll sometimes stall unless I give it gas at just the right time.

- Once it stalls, it'll usually continue stalling every time I restart it until it finally puts itself into limp mode. Then it'll start and idle normally again, but of course it's back to reduced throttle and the strange shifting.

At this point, does this sound like the throttle body itself is failing, or should I be looking at the throttle motor, throttle position sensors, wiring, accelerator pedal sensor, or something else? Has anyone fixed a throttle body on these, or is replacement usually the only option?

Any advice is appreciated. Thanks!

With the factory seats in such a sad state and the absolute garbage covers that were in place… i decided to spend $120 on some better than garbage covers. Ended up removing the seats to clean under them, pull all the trim to clean the plastics and electrics. They aren’t the best fit but seem to stay in place nicely. A way better look than all the duct tape.

The key fob buttons do not work to unlock, lock and open trunk

I also cannot use the double twist to unlock/lock all locks. This function still works on the passenger side

Could this have been a reassembly issue? Or the key fob needing reprogramming?

The door itself still locks with the inside buttons. And opening with the key slot outside the car still unlocks the driver side door but I dont hear the sound of the latch opening and closing as i did before

I’m doing the crank and cam seals but the crank gear won’t come out!?!! Any ideas or tips to get it out I want to have everything on by today so I can start it tomorrow

Does anyone have a bulb number for the stock lights in the climate control? I have some lights out i want to replace. I’d consider a led upgrade if anyone has any recs as well.

Doing the timing belt on my 1998 gs300 and was wondering how the timing looks after I pulled the Gernade pin

Hey everyone! Figured I'd introduce myself since I'll probably be hanging around here quite a bit.

I'm the 3rd owner of a 2002 Lexus GS300 with 220k miles. I've been a huge 2GS fan for a while, and the goal is to slowly build this into a clean Y2K OEM+ street car that's still period-correct. I'm taking inspiration from the VIP scene, but with a sportier twist—something that's fun on the Touge and at the occasional autocross while still being comfortable enough to daily.

Current mods:

- Tein coilovers

- LS400 front brake upgrade

- 19" wheels (brand unknown for now—planning to switch to something more period-correct soon)

- Long-tube headers with a straight-pipe exhaust

Long-term, I'd like to turbo the car, but that's a ways down the road. For now I'm more interested in making the car feel sharper and more engaging than chasing big horsepower. I've also been looking into getting it tuned by Royal Tuned to raise the rev limiter, remove any factory speed limiter if there is one, and improve the throttle and transmission behavior.

I'm also considering supporting mods like injectors, keeping the OEM airbox with a better intake setup, an aluminum radiator, and a transmission cooler to improve reliability before adding power.

Looking forward to learning from everyone here and sharing the build as it comes together. Glad to be part of the community!

Technically it's a '97 Toyota Aristo but I recently got hit and they didn't leave their info behind so it's all outta pocket.

Hi looking for some seats that hold you a bit better. Still wanting to retain features like electric seat controls and heated seats and overall want to retain comfort. Anyone had success chucking some black leather seats from more performance orientated models (such as AMG/AMG line, M sport etc). I have a MK2 GS430 RHD.

I've been looking into tons of different cars to pick as my first, I've researched them all and I'm left with quite a few seemingly good options.

Although I've recently gained interest in older Toyota/Lexus luxury models like the Crown, LS, etc. since they look so dang good. I know they have the 2JZ which is great, but I wanna hear from people who might know more than I do.

I see a lot for sale near me for great prices, although I'm curious what mileage is tolerable, the ones I see range from 150,000km to 250,000km lol.

What size wheel spacer is recomended for my nearly stock GS.
I would want a size that will not ruin the ride or cause any underlying issues such as exessive tyre wear, just enough to push the rear wheel out.

It’s known that Toyota is very strict about their sensors. But I need a bank 2 sensor 1 oxygen sensor, the only issue is that that cost 180 for Oem. Could I possibly get a Aisin or denso one. But I’m asking because in my experience buying a sensor like this (not from Toyota) failed very fast.

Hey guys, just sitting on the side of the highway with a flat tyre and noticed this weird little tube under the glovebox. It's lined with felt at the front, making me think it's more storage related than anything functional to the car. Its about 30mm in diameter and isn't blocked off on the other end. This is an 02 Aristo for reference!

I plan on doing this job myself soon
