Thanks. I'll do that. So you think it's unlikely the seals around the glass roof leaking?

Yes its leaking slightly into the headlining

Hi All After some advice please. My GS300 sunroof is starting to leak water around the sunroof... I think the seals around the glass sunroof are worn and need a new seal around. Any idea how I can reseal? I couldn't find any seal specific for this car. Can I get get a universal seal and fit around the glass? Just after some advice on how best to approach it and type of seal I need? Thanks all!

Hi Matt - Lovely looking LS400! I had one a few years back, sold it but I really regret it. I should have kept it 😞 Love the wheels too!

Hi Matt They are rare wheels, its hard to find the staggered wheel set. I've got a set on my GS300 Mk1. Even rarer to find one that hasnt been welding etc. Are you looking to sell them?

Looking for a ECU for a 1st gen GS300 1996. Got some engine start up issues and a few car electricians have said that it might be a faulty ECU. Thanks Jav

Hi All. The cars back at home now parked up. Mechanics gave up on it and sadly no body has been able to diagnose the issue. Its off road now and will try and see if I can get some other mechanics to look at it but for now taking a little break.

Yes security light goes out, we don't believe it to be an immobiliser as the start starts and can give it a few revs before it cuts out. Once it cuts out then there's no sparks. Does you or anyone else know if I buy a replacement ECU module, does it need to be reprogrammed? The conclusion so far is its some sort of signal issue somewhere. My mechanic has given up on it and my only option is now to book it in at main Lexus dealers....

Hi Colin. Thanks for your reply. The mechanic did a diagnostic test (the old school blink test). No errors came back at all. I was hoping this would pick something up but no joy sadly

Thanks Jon Dee. I will pass this info onto my mechanic. My last option to consider is buying another GS300 and doing a full engine and electronics switch over. It will cost me some money but its a car I want to keep alive

Hi All I'm in need of desperate help to save my beloved GS300 sport 1996 MK1. The car starts and cuts off within a few seconds. Been with a mechanic for 2 weeks and no joy. I have changed the following but still issue persists! Distributor Crankshaft sensor Ignition coil pack Ignition ignitor Sparks Can anyone help or recommend anyone who could look at this? I really want to keep her alive and on the road but I've hit a brick wall! I don't want to end up selling her for parts. Any help is appreciated. It's GS300 1996 mk1 sport. 2JZ GE engine.

Spent some time the other day re doing the black trim around the windows and front windscreen. The black had turned into a dull grey over time. Gone for a black glossy look. Pics of work in progress, will post pics of once all completed.

Thanks. Yep doing my best to. It will be a keeper for a while. The engine is so quiet, smooth and gearbox is silky. Lexus really did a brilliant job with this first gen GS300!

Hi All I've owned my Lexus GS300 MK1 1996 Sport for 8 months now. Absolutely love it. Had new springs fitted All wheels fully refurbished Brand new tyres Machine Polish Full Service done Not many of these MK1 GS300 Sport around, doing my best to bring it back to really good condition and keep it completely stock. Its a dream to drive and has the legendary 2JZ GE engine - super smooth. Enjoy :)

So had lambda/o2 sensor replaced but problem is still there! This is exactly what happens: Starts up fine when I start car first time for first use. After driving a while, turn engine off and come back to the car after a short while then starts up and cuts out straight away, start again and doesn't crank just keeps ticking. Take the key out put back in and starts and cuts out. 10 15min later starts normal Driving me nuts!
