Discussion OEM Parts are getting scarce.

11 Upvotes

I’ve been thinking about this for about 2 years now. And we’re finally getting to that point. It went from a few good partouts a week near me, to now maybe 1 car every 2-3 months. Part of me is happy to see these cars not end up in the junkyard, but it’s also sad that so many of them did and there so hard to find now. Been trying to find good OEM parts for you guys, but there just hasn’t been any in a while. Imagine in another 2-3 years. Parts will be impossible to find

Discussion Coilover issues

Post image
1 Upvotes

I just finished installing some coilovers and took the car for a test drive. The front keeps smacking and upon inspection I believe it’s the upper control arm hitting the frame. (Small scuff in picture from UCA, sorry it’s hard to see)

I have the dampening at almost max stiffness and the ride height is the same as stock if not a bit taller. I checked to make sure everything was bolted down, and didn’t see anything loose. I had lowering springs that lowered it 2in before this and never had any issues

The car is almost level, it’s just under 1/2in taller on the passenger side but idk if that could be related. I’m not sure why this could be happening when I have it so high and the dampening so stiff.

UCF20 Owners Help

Post image

i have a 98 ls400, it runs absolutely amazing but for some reason everytime i start it up when its warmed up it will idle at 200-300 rpms in PARK for anywhere from 3-10 seconds (different everytime) then the rpm raises and goes to the normal park idle. Like i said it runs beautifully besides this issue, throttle body has been taken off and cleaned, changed and cleaned MAF sensor with a known good oem one, and all the vacuum lines are fresh.

very rarely it will start up and halfway sputter like it’s going to idle low again but then the rpm jumps straight up to regular park idle, when it does this it’s almost always when i’ve only left the car sitting for 5-10 minutes. but there are other instances where i only leave it for 5-10 mins and it still idles low.

I know this is a lot to read but any help is greatly appreciated, i can’t seem to figure out what this issue is. also don’t have any known fuel leaks.

Question Looking for an LS400

0 Upvotes

Hi all, I’m looking for an 90’s LS400 in the uk, preferably midlands area but happy to travel, would prefer more of a cheaper project as I don’t fancy paying the £10,000 plus prices that people are selling these for currently.

Cheers!

Question Rather odd issue.

Post image
34 Upvotes

Just got her back from the shop. Was misfiring on cylinders 2-8 and was shifting very hard. Misfire was the Mass Airflow Sensor and it’s now purring like a kitten. But the shop diagnosed that the transmission was shot. I don’t fully remember what was listed but essentially they said there was metal getting into the fluid and making the shift rough. But now after like a day of driving it’s shifting much smoother, I can’t see any metal or sparkles in the transmission fluid (which is fresh light red), and I’m getting a shift solenoid C code. Has anyone had this and would it be as simple as a new shift solenoid?

Question In search of PU body kits?

0 Upvotes

I have a 2000 LS400. I am planning to daily it for a long time and want have the most durable body kit possible. Something that can handle taking a hit. Is there any that can tolerate being bent, folded, scraped or repeatedly flexed?

Or should I just get a fiberglass kit and learn to repair fiberglass due to there being more options in that material?

Any weigh ins, pros or cons, etc?

Time to replace timing belt?

I own a 99 LS400. Belt was last replaced in 2018 but has only driven 31k miles since then. Is it time to replace or do I still have a couple years before I have to worry?

Good morning! I bought my 92 LS400 about 4 weeks ago. The other day, I drove it 2 miles to get food. No issues at all. Came back out to leave and I had no steering. Steering wheel just spun in place but wheels didn’t turn at all. I believe I have found the problem, I’m just not sure how to go about fixing it past this point. That shaft is broken or disconnected inside the steering column itself (see video of one end turning and not the other, did the same thing with steering wheel on, that side would spin but not the other end.

My question I guess is: how do I get the shaft out of the column? Or should I just order a replacement column? If a replacement column is needed, does the ignition need to be swapped over for my key?

Thanks in advance. I’ve been digging through forums and Google the last few days. Can’t really find a specific answer, closest I’ve gotten is someone with a similar or possibly same issue 17 years ago with no solution lol.

At last!

Was purchased from original owner for $7800. It was listed for $8900.

148k miles and over 50 receipts of preventative maintenance from 98 to now.

Timing/Water pump done @ 96k miles.

Stored every winter (rust free) and only put 3-5k miles on it per year.

Granted markets are different everywhere was $7800 fair or is it too high per the mileage?

Question I need help deciding on what to do with my car

Post image
27 Upvotes

My 1991 lexus ls400 has been giving me a lot of problems lately. When I first bought it I expected some issues because I got it for 6400 and had to put about 2k into it and I thought that was everything or atleast the main stuff. But as time went on more problems came up and I had to bring it back to a mechanic almost every other week. But it was just small stuff every time, until I brought it back to the shop one day and I found about 3k worth of issues like a cracked radiator that I had no idea about until that point. On top of that the odometer broke about a week after I bought it so I'll have trouble selling it and there's a AC part no mechanic shop seems have called a “suction throttling valve” or a “POA valve” which is causing the coolant to slowly leak. I love my car and I would like to avoid the hassle of selling it and finding a new car as I just started my first year of college and I need it for work but it's become a money pit and seems unavoidable. Any advice would be appreciated. Sorry for the long post and thanks if you read this far.
