3rd gen GS300 with 98k miles has occasional rough idle on start up as though not running on all cylinders. It clears under load quickly and is very intermittent. Car has been serviced and had new plugs about 6 months ago. No fault codes showing up.
It also seems as though the transmission changes to a higher gear too early. i.e to 5th or 6th at around 1200 rpm at modest speed when it feels like it should hold it for longer. No other problems with the transmission and changes seem smooth enough and works fine on sport/manual shift mode.
Seems more like electrical gremlins than mechanical.
I have a got a slight blow on the exhaust at the very rear but I cant see that affecting transmission or idle at start up.
Any thoughts or obvious things to check. I am not familiar with the GS300 engine and it baffles me how a transmission fluid can be 'for life' and I cant check it.
Hope you are well,
I would be very grateful if you could help me, please,
I own a 2000/W reg. is 200 with auto box
I paid £800 for the car, and have the car for 6 months (probably the best / fun/ 6 months driving I have ever had)
My wife was driving my car (no that wasn't the bad news) and she stopped at a T junction when she came to pull away the car would not move, the engine was running well, but it was like car was in neutral when I arrived 1 hour later I started car and it was back to normal for 200 meters and then back to "being in neutral" The AA man who towed me home said "It looks like clutch "had gone"
2 days, later I had to move car 100 yards, and it was fine again in forward and reverse,
There have been no warning signs of clutch/gearbox problems,----- burning smells,crunching noises, struggling on hills,
Also the engine management light was on when car was "in neutral"
I have heard stories of £1500 - £2000 for clutch and gearbox work, but even though I love my little Lexus, I would not pay this on a car that is now worth £400 - £500,
As anybody got any ideas what this could be ?,
I don't want to be patronised by the half wit at the scrap yard offering me £40 for my pride and joy and then tell me he would not make anything on it then sell 1 leather/heated/electric seat for £80,
to then drive off in is 6 series Beama (sorry to go of course a bit, but they really do frustrate me).
I don't want to scrap car if it was be a small issue costing only a few hundred pound.
Any help would be gratefully appreciated
Hello everyone, I'm new here, sadly my first post is about an issue I'm having witih my beloved 2004 SC430. I'll detail the problem below as the techs at my local dealer can't seem to suggest anything but gearbox replacement, I'm hoping to find a cheaper solution for my troubles.
So it started happening a few months ago. When shifting from 4th to 5th gear the car jerks, the higher the rpm the harder it jerks, it kind of lunges forward for a moment. This stuff becomes quite violent at high speed. It also sometimes does it from 3rd to 4th. It only happens after the car is warmed up, never when cold. At first I changed the gearbox oil and filter, and indeed shifts are smoother but the problem hasn't gone away. Has anyone had similar problems that could me some advice on what was wrong? My car has only 90k kms, it's been in the family since it was new, nothing ever happened to it, and was always well maintained.
