excellent... thanks guys for the help... i'll try the above..

Hi All,

Firstly Happy New Year.

Next, i've got the common issue of a sticking front caliper on my 95 GS. I've trawled the forums and internet and found someone recommending Brakes International for the repair kit but i can't find one listed on the online shop..

Am i missing something there or is there an alternative (non-dealer) supplier for the kits?

Many thanks,

Nick

Or you might need something similar to the flange adaptor shown in this page clicky

flange kit is available on this link clicky

thanks mate.. yep its the flange kit i need.....

oops!

Hi All,

Hopefully you can answer a question for me on something i may have overlooked.

I have a '95 GS300 Sport with 113k on the clock and i decided to change the Oxygen Sensors after hearing how they can make quite an affect on fuel mileage etc (and mine is pretty awful)

Anyway i found my sensors are 1 wire ones so ordered a pair to go on the exhaust manifolds.

After removing the heatshield i found the old sensors are held in by a flange and two bolts where the new ones have a 22mm nut which screws in..

Do i have to buy special sensors with flanges (which i couldnt easily find) or can i adapt the ones with the 22mm nuts?

Any advice would be greatly appreciated asap as i need to know whether to send the sensors back..

thanks all,

Nick

This is what it says in my electronic manual for timing adjustment (Note that this is an american version but would assume ignition timing would be the same??)

IGNITION TIMING INSPECTION AND

ADJUSTMENT

EG4MC–01

1. WARM UP ENGINE

Allow the engine to warm up to normal operating temperature.

2. CONNECT TACHOMETER AND TIMING LIGHT TO

ENGINE

Connect the tester probe of a tachometer to terminal IG􀀀 of

the DLC1.

NOTICE:

• Never allow the tachometer terminal to touch ground as

it could result in damage to the igniter and/or ignition

coil.

• As some tachometers are not compatible with this

ignition system, we recommend that you confirm the

compatibility of your unit before use.

3. CHECK IDLE SPEED

(See step 3 in idle speed inspection)

4. ADJUST IGNITION TIMING

(a) Using SST, connect terminals TE1 and E1 of the DLC 1.

SST 09843–18020

(B ) Using a timing light, check the ignition timing.

Ignition timing: 10° BTDC @ idle

(Transmission in neutral position)

© Loosen the nut, and adjust by turning the distributor.

(d) Tighten the nut, and recheck the ignition timing.

Torque: 19 NVm (195 kgfVcm, 14 ftVlbf)

(e) Remove the SST from the DLC1.

5. FURTHER CHECK IGNITION TIMING

Ignition timing: 7–19° BTDC @ idle

(Transmission in neutral position)

EG–16

ENGINE – ENGINE MECHANICAL

HINT: The timing mark moves in a range between 7° and 19°.

6. DISCONNECT TACHOMETER AND TIMING LIGHT FROM

ENGINE

There is definately something effecting the mpg badly, I've just driven down from Derby to Dorking on £25 (152miles @ 29.8mpg).

Thanks alot for posting all that info.. Yeah sounds like something is upsetting the MPG in a big way..

Well i think O2 sensors will have to be the next course of action as i would imagine the car is on the original ones at 110k+ miles.

thanks again for your efforts.

Nick

hi guys,

well i've checked tyre pressures after a chat with a few people on here and am running 34psi allround on the 18" sport wheels..

I read the Oxygen Sensor thread with great interest but we never heard in the end what the final result was with regards to fuel economy and performance. The original poster seemed to go quiet at that point...

I've found some very cheap sensors on eBay (new universal 4 wire ones) and may give it a try..

I dont have a workshop manual for the Lexus but does anyone know what the timing should be? May be worth giving that a check since it seems to use conventional distributor ignition..

Currently £30 of 1.04 unleaded will do anything between 110 and 130 miles.. even driven like captain snail in snailville

I've found the air filter has made a huge difference on mine. I've just fitted a K&N panel filter and have noticed a marked improvement in MPG even compared to mileage just after changing for an OEM filter. Sitting at 70 on the motorway I now get 33mpg (not tried 80 but i wouldn't expect it to be a long way off the 33 at 70 from previous checks before) and average 26 on mixed driving. This is about 10% above what the OEM filters were getting just after being changed. Consumprion dropped of quite quickly I found with the OEM filters as they clogged. I would think the 02 sensors could do with looking at as the next step. I'm not sure what fault codes if any would appear if an 02 sensor has not completely failed.

I would tend to think that the performance issue is more getting used to how the car works. If you are saying you plant the accelarator and kick down, and the car is performing as you would expect then I can't see that it can be anything else. If you plant, kick down and the car is going nowhere, then it could be the car, but I don't think that is what you are saying Are you using the ect/pwr mode? This does make a massive difference on mine to how responsive it feels. In normal mode, the gearboxes eagerness to keep revs as low as possible is extremely annoying and the amount of kick down required to get it going again is sometimes quite worrying. i.e. kicking down from say 4th to 1st has an horrendous delay which can make you feel stranded if you have pulled on to a roundabout quickly but had to let up slightly. Before you know it you are in 4th and the car doesn't want to make haste again quickly. ect/pwr mode solves all of that so I tend to not have it in any other mode.

Shake, no snow mode on our older GS's mate :(

33mpg???? holy mackerel. Honestly, even driving like 'Miss Daisey' i managed to creap up to 21.5mpg. 33 would be a miracle..

Well its not bad on kick down but nothing special. I dont cruise around in pwr mode because obviously MPG is pretty dreadful anyway and leaving it in pwr mode would just make it worse..

I'll replace the O2 sensors and maybe try a K&N before i give up and go back to the 'german side of the force'.. shhhh dont tell anyone..

hi

with mpg you cant expect much. its an old engine (technology wise). driving at 70mph uses less petrol than when crusing at 80. i've found driving in snow mode helps with mpg.

at the end of the day we've got motorway cruisers not race cars. most torque is produced at 4k-5k rpm. i kinda know what you mean when you say you have to bury your foot around the 60mph mark, i reckon theres a flat spot there. although i've noticed when in pwr mode the car holds revs longer so when you want to go theres no kick down as its in the suitable gear already ... the car also has a learning ecu... if you drive gently to save fuel it will learn this and help so to speak... drive it hard for awhile and it acts more potent!

the best bang for buck in my opinion is TESCO 99RON PETROL!!!! (also get more miles out of it)

what petrol do you use?

Hi there,

yeah i kinda guessed it being effectively the last series N/A Supra engine it would be fairly old school.. (Iron block straight 6 and all that)

I'm running Esso normal 95 ron. when you're churning it up at 20-21mpg you tend to go for the cheapest.. :-)

I've just heard of people getting mid to late 20's on a run and i see nothing like that..

On the performance front i didnt expect it to be startling but i've struggled to keep up with even pretty mediocre cars and that hurts somewhat when they are doing 30-40mpg+ and im doing 20...

Could be a very short love affair with the lexus at this rate :(

Hi people,

well i've had my '95 GS300 Sport for a few weeks now and its a great comfy car but i am experiencing a couple of issues which may be linked..

Notably i seem to get 21mpg regardless of how i drive it and includes quite alot of dual carriageway work.. i mostly cruise around 80mph and have been driving gently to try and get the mpg up a little..

The other issue is the car seems pretty sluggish.. Its ok from a standstill (which i thought is where it would struggle with its weight etc) but once on the move (50-60mph) it seems you have to bury the throttle and kick down to get any kind of decent progress.

So far i've replaced the front disks and pads (as were getting low) and serviced the calipers so i dont have any sticking issues.

Oil and filter has been done along with a new air filter.

I've reset the ECU as advised on here (many thanks people) and i've checked my ECU for fault codes with the trusty paperclip but all appears ok.

The car is on 113k so not huge mileage. Also the car runs smoothly with no misfires in the rev range.(so i dont suspect bad leads or plugs) Just very sluggish.

I've read with great interest people talking on here about the O2 sensors but no-one has reported (from what i can see) that their cars have actually driven alot brisker than before replacing them.

So im rather at a loss...

Any suggestions please people?

many thanks,

Nick

had a look, it seems his auction has ended....

if i see it again, i'll let you know.

best of luck

thanks alot mate!!

If anyone else has a pair of 10" going please let me know. I'm at tyre changing time so would be a good time to get the wheel situation sorted.

thanks,

Nick

Hi there,

looks like a great job mate.. and at the end of the day what isn't visible, so long as its strong doesnt matter in my book.

Do you have the part number for the toyota facia? i think i may go down the same route myself.

But does look good...

rgds,

Nick

Instrument Panel - Part No 55412-30430 (fascia plate) about £15 + vat I think.

Radio Cover - Part No 55521-32011 (cubbie hole) around £23 + vat or there abouts.

Cheers

Rick

Top man.. thanks for that!

hi,

theres a person breaking a gs mk1 with sport alloys on ebay. though he only has 3 alloys i cant remember which ones as i wanted a full set.

good luck

Ok.. i admit it i'm rubbish searching on eBay.. i can't find the guy.. do you have the seller or item number to hand?

thanks,

Nick

Many thanks for info.. i'll have a trawl for him on eBay..

Decided to bite the bullet and take the wire cutters to the factory wiring. The amp and CD changer are now in the shed, and the Sony unit is playing through the factory loom no problems with my ipod hooked into it. Only thing I haven't done yet is the antenna, will do that in the morning. Vibe sub is working too although I need to take the factory sub out which should give some sound flow through into the cabin. Something is vibrating like :tsktsk: as well when the sub is working hard so need to find that too. All in all, even with the sub turned off, the sound is 1000 times better than the factory unit, I'm quite impressed how much bass even the standard door speakers can kick out.

I'll put up the wiring colour coding and what I joined to what later on.

looking to fit a dobble din dvd palyer in my 1994 gs300

just wondred what parts do i need an can u still use the std amp an sub

regards gary

sorry dont have an answer for that one but would be interested myself.. as i'd like to bring my Stereo into the modern age. :)

well the answer to the survey was 3 were on 25psi and one on 16.5 psi.. No wonder she felt a little odd! :)

On a positive note its amazing how forgiving the lexus suspension is as it drove alot better than the figures suggest.

thanks all for your help...

i'm going with 34psi allround for a while since often its only me in the car so very lightly loaded.

cheers,

Nic

Hi Nick,

Mine has the 8.5" all round and I run 34-36psi depending on load and road conditions. I've spoken to Tony @ WIM when he set my suspension geometry and around this sort of pressure is about right. The regular GS is 32psi all round for general conditions but I think the UK dealers modified them to create the Sport model and there wasn't a specific tyre pressure.

HTH,

Dave.

excellent... many thanks for that... mine does feel rather skittish so lets hedge our bets what mine are set to..

thanks,

Nick

I'm running 245.40.18 front,275.35.18 rear at 36psi all round with myself and wife in car. I tried various pressures and found these gave good ride and handling. I have been unable to find any official pressures in nearly 6 years of owning the car.

thanks Dave,

i'll have a compare with mine

cheers,

Nick

Hi All,

Apologies if this has been asked many times before but i've trawled through the searches and not found an answer.

Does anyone have the correct tire pressures for a MK1 GS300 Sport with the 18" Sport wheels.

All four are currently the 8.5" wheels....

Any info would be appreciated as i think the previous owner got the pressures round the twist and its feeling rather skippy at the mo.

many thanks,

Nick

Hi All,

Yes this has probably been asked a thousand times but you have to ask.

I'm looking for a pair of Mk1 GS300 Sport Rear Wheels ... the 10" wide ones..

I have the standard width ones at the mo and its new tire time so would like to upgrade to some 10" ones.

Does anyone have any or know of any? This is a genuine enquiry so real money waiting..

Many thanks,

Nick

If you havnt fixed the probs yet try this.......

Before you rip the aerial apart, Try oiling the mast with WD40 when its fully extented, This will clean and lubricate it...

Regarding your speakers, Is your tweeter in the door ??

If so check the loom going into the door you may have broken or corroded pins. Or maybe someones messed about with somthing in the door and never connected them.

I think its the easiest and quickest thing to check before rou take the whole centre of your dash apart.. I have a feeling this is where your problem is........

Regards, P

Hi there,

I'll give the mast a good clean with WD40 and see how i go...

The tweeter is on the door at near mirror height. I'm not getting any sound from this speaker or the larger speaker in the bottom of the door so my guess would be either a loom problem going into the door or the connection at the back of the head unit.

Is the 'door loom' easy to get to?

many thanks for your help,

Nick

Have a look at this link mate for doing the AC Control bulbs, the stereo head unit comes out as part of that. Make sure your security code is off or you know what the code is before disconnecting the stereo though.

clicky

There is a feature on the car that feeds the optional mobile phone stuff to one of the doors for hands free, can't remember off the top of my head which door though. Maybe there is a partly disconnected mobile phone kit forcing the speakers off from normal audio expecting the phone audio instead. Might be the wrong door but just a thought.

Excellent... thanks alot for that... i'll double check the security code issue as a stereo without any sound would be much worse.. :-)

sorry to resurrect an old post but looking at the universal O2 Sensors from Cats-Direct, which of the two 4-wire O2 sensors do i need? the one with the two white wires (i.e. black, grey, white, white) or the dearer one with Black, Red, White, Yellow???

I need to order some for my GS300 Sport Mk1 '96 which is currently running low on MPG... (19 even on a run!)

If someone could answer on the quick that would be greatly appreciated!! :-)

regards,

Nick

id take out the aerial its simple enough , might needs re inserting , mine over the cold weather, only went up about 9 inch, and stopped about an inch off being flush, might be some crap on the teeth, simpe to do. as for the speakers, cant help you with that im affraid :(

i think there is instructions on here somewhere how to remove the mast

if not give us a shout

oh , welcome to the club

Thanks alot for your help... i'll give it a go!

Im guessing on the sound aspect i may need to remove the head unit and check the connections... does anyone know if the Air Vents are hard to pop out on the MK1? i understand i need to do that (among other things) to remove the head unit....

cheers,

Nick

Hi everyone,

This is my first post on the site so first of all. Hi everyone.

I've recently acquired a '96 GS300 Sport which runs like a dream but i have a couple of audio problems.

Firstly and most important is that there is no sound coming from the Front Right Door Speaker & Pillar tweeter. All other speakers appear to work fine. Would you suggest checking the wiring to the speakers or the connections to the back of the head unit?

The audio ia apparently the Premium Audio with the 12 CD changer in the boot.

Secondly the Electric Ariel doesnt go all the way flush with the boot. It stops about 6 inches above. Is there an easy way to sort this. It goes up and down fine other than that.

Anyway, Hi again averyone and thanks in advance for any help.

regards,

Nick

any ideas gang??
