car care nut is the guy to talk to about the vehicle issues.

We need more ls460 videos on the internet. This is up there on the list of the most yakuza gangster cars ever made 🤘🏽

I dealt with this exact issue, but I have a 2014 Lexus GS 350 F SPORT AWD. It is worth noting that they have the same fuel D-4S injection system with both the direct and port fuel injectors. Myself, I had to replace the direct fuel injectors. An advanced Lexus specialist worked on the car and I know him personally and was able to fully articulate why it was specifically the direct injectors and pointed to the fuel trims. I would recommend getting your car diagnosed professionally. Not trying to say that it might be just your direct injectors, but I honestly think that might be the case given the similarity.

I recently did a coolant valley plate re-seal on a 2014 LS460 AWD due to a coolant leak, and while disconnecting the direct injector harness one of the direct injector connection points snapped clean off due to how brittle the plastic became over 100k miles of heat cycles. Our shop had to eat the cost of the injector and it was nearly 500 dollars just for one injector, teflon seals (which require a special tool to install correctly), and the o-rings for the rail side of the other injectors. My advice... if you do take this job on yourself, be VERY careful when disconnecting the direct injectors and the AWD harness does not come fully out of the way due to the starter wire harness being blocked by the exhaust manifold, but you can free it up enough to use a bungie cord on the hood latch to get enough space to work the intake out. May also want to consider having the dealer install those teflon seals on the tip of the new injector for you as doing it without the special tool seems like it would be a nightmare.

Sorry to hear that. Hope everything turns out well for you 🙏

Love your videos on the LS 460

Hey Marty...I'm not sure, but if it has direct injection, then it may be some carbon build-up inside the intake manifold. If the issue persists under moderate to hard acceleration, then check your fuel injectors and connectors, which are prone to becoming brittle and breaking causing issues. Best of luck with your awesome car.

new to the channel, love the car and the channel. excited to see this car as time goes on, great work

Having the same issues on my '02 sienna with 330k plus. Replaced the spark plugs and coils on bank 1 with denso parts and I'm still getting the codes. At least it's running a lot better tho and not like shit anymore lol

I’m sure you’ll have that LS sorted out in short order !

Lol. I checked a Lexus Owners Chat, and 1 Person changed Head Gasket ( after Spending Thousands of $ at Lexus). He Claims that it Worked.

Also please make more videos on this car because i can’t find anything on this car nowadays, just subscribed thanks

Good looking ride. Hope you figure it out

I hate these no-see-ums in the engine bay. I recommend looking at any ground cables and bolts for corrosion and fraying. Though a ground problem would be less likely to be cylinder specific. Also there could be a wire in the harness leading to cylinder 6 coil or injector that could have chafing or rodent damage, causing a grounding short. Injector harness cable is thin and subjected to so much heat and vibration that it's one of the first things I look at when I pull an intake manifold off. I've wrapped a few here and there with electrical tape to give them a little extra time to live.

Hey man! I got the same car 2013, i was just curious as to where you blacked out the key?

Had the same thing happen to my 09 gs 350. Replaced cylinder 5 and 6 with new spark plugs. When i punch it the engine light comes on. I traded it in yesterday and got a 2017 gs. Good luck!

Frankly I like the (relative) simplicity of the 3uz in my ls430 and the 2uz in my 4runner

I wouldnt be a bad idea to do a smoke test before you start tearing it apart just to pin-point any vacuum leaks that you may have. It would say its very likely a direct injector but checking for any unmetered air could save you some work.

Sounds like a sound diagnostic plan is in order. Always better than unloading the parts cannon.

My IS350 was doing the same thing but I was getting a misfire on cylinder 1. I did the same as you but I added Lucas complete tune-up fuel injector n drove it until the gas light came on replace all my spark plugs... She been running find.. don't know if that my help out.

Nice ride. Love that black on black even though it will cook you where I live! Lol. Got the same year model but 2 wheel drive and not a Sport. 215k. Got run off the road into a metal light pole (not much damage, barely touched the hood) and all of a sudden It act like it don't want to stay cranked and I'm getting a code for the knock sensor. Looked at that job and I can't say I'm real eager to pull the intake off. On the fence about doing it myself or taking it to a shop. Anyway, don't listen to everybody coming down on it. That car can go a long time with proper maintenance.

Had the same issue. Not only did i had to replace my spark plugs, clean fuel injectors from carbon build up, i also had to reset my ecu/computer. Seem to have done the trick.

My 2019 accord had the same issue. Mine was most likely the motor after the fuel injectors were replaced. Hondas turbos have issues and mine didnt make it to 100k. at least its working mine was shaking horribly and very low power. got rid of it before the light stayed on solid

direct. injection is a problem becasuse clogs :/. I had a is250 with similar issue,250k i also i had a GS350 with no issues. :) 170k . good luck hope you get it worked out!

This is really why I have not bought this exact model which has been my intention for the longest time. You’re better off as I don’t have the background you have in engine mechanics. I really like this car but know that to get one these days would mean it would have tons of mileage. Good luck and hope you get that issue sorted out.

When you purchased the car did the seller say anything about the check engine light coming on?

I was at A car dealer 04/20/24 they had this same car sitting in the corner on SALE for $20.000 I said that MONEY PIT WILL NEVER SALE!!!😂😂😂

I’m, what happened with the ISF??

Honestly do you regret purchasing the vehicle ?

I would try a very strong fuel injector additive I know amsoil and royal purple have strong fuel injector additives see if it helps it before spending big.

Do a compression check, you’re dumping a lot of money in to that vehicle where the previous owner most likely did the same he’s just not letting you know about it. That’ll at least mark off that engine is good and makes it worth it to dump money in to it

So would you recommend this vehicle? Or wouldn’t?

I had this same issue on my is350 and it was a clogged catalytic converter. Only happy under WOT and would cause misfires. I was thinking it was fuel related the entire time but wasnt. Hopefully its an easy fix for you

Bro that little oil leak where the tranny meets the motor .. is causing the car to go into limp mode .. due to low oil pressure.. you have to drop the tranny and fix that seal

Did you pull the lexus service records? I wouldnt be surprised if someone put bad gas in it

PLEEEAAASS when recording audio, please record in MONO and not stereo. i hate how your voice is bouncing around in my headphones. makes watching video so much harder when the content itself is good. also run Seafoam in the gas. while it may be a dead injector, seafoam clean out the internals of the engine. When we got my moms 09 Camry xle, we ran seafoam in the gas for a while and, the car after a couple of fill ups, ran much much better. far more responsive and MPG kicked up a little bit as well

How is the timing belt might have slacked

run the injector through a ultrasonic cleaner if you have one and see.

Take it to the dealer. How hard is that?

That thing IS clapped out a bit BUT it is fixable with all new injectors I think..

Damn! At this point you might as well put in a super charger since you’re taking apart the engine.

Nice ride… but toooo much miles man lol

You literally have the same 2 vehicles I have

Consult with the youtuber/mechanic "the car care nut"

Maybe the cats are clogged? put a borescope in the cats through the sensor

Dem triple beams is a rare option.

So much for Lexus reliability

#1. I would never buy a luxury car with that many miles. I would put 2-300,000 miles on a Lexus but I would never buy one with that many miles. #2. I would never buy a car from NY because of snow/rust and people in NY that sell cars always seem grimy. #3. If im not mistaken, you paid for the car before you drove it. Big no no.

The best first mods are the necessary ones! You got this brother. I'd recommend you bring that car to Scotty Kilmer! I'm sure he'll remember you and help you out here. Maybe vacuum leak? Have you tried ATS Carbon clean for your engine oil? That'd be a more direct approach instead of fuel tank. Hope this all helps! Hoping to see you ripping the streets in PA soon!

Sounds like the seller screwed you.

😢😢😢

Just a suggestion. Maybe you can take the entire set of injections cleaned out.

Know good and well you don’t use that gym

Time to retire the other car the landcruiser with so many miles

Part out, get a BMW

Typical poor quality from Toyota should have got a Hyundai
