Amount of detail you pointed out it’s crazy
Thank you very much 👍🏻
I have to do this in next few months my rpm in the morning when car is cold are very high and even when I stand on red light
I’ve seen cold engine engine idle going to 1500-2000 briefly and it’ll settle back to 650 area once engine warms up
But idle going high while stopped at a light after engine has warmed up is unusual. You might have to clean the Throttle Body and MAF (mass airflow sensor) I have video on those as well
@@DIYLifeSkills that’s great idea thank you
This is a very accurate description of how the process is.I probably broke 10 connector clips during a similar job! Cheaply made and frustrating to work with!Thanks for the video sir. I subbed you🙌🏻
@DIYLifeSkills Hi I was wondering if you could help me out with something at 13:39 you mentioned the two connector one with a hose. Can you tell me where the other end of the hose connects to? I took the intake manifold off but There was no hose connected to it.
I need help finding the torque specs for Valve Covers for a Lexus is250. Engine is 4gr fse.
OMG so much🤯work, thanks for the video👍🏼 I hate i got this gs 300 fast but to much maintenance.i should have paid more money for a gs430😞 or maybe a GS 350 because I never had a GS.only ES300and ES 330 and LS 400 and LS 430 best cars I ever had 😊😊I'm still a Lexus man💪🏼 but i see even lexus makes lemons sometimes 😮
Yeah up to 2006, GS300 had GDI (gas direct injection) which is prone to carbon build up in intake valves. Starting in 2007 GS350, they have dual (direct and port) injections, so there is not intake valve carbon build up. Not sure if GS430 had dual injection also. Other than the GDI carbon build up issue, this has been a very reliable car for me.
Bonjour que penser vous de XENUM Intake Pro Petrol ? J ai pas envie de tout demonter
Wow, someday i could try this
when all those extra connectors are prepared.
And watching this video 10times at least. TY for share the job
06 GS300 is GDI engine, so it‘s prone to carbon build up. But 07 350 is dual injection, so the carbon build up will be much slower. I wouldn’t worry about it until it get close 200k miles on your car.
@DIY & Life Skills Oh i see. .
i thought those two were almost
same except for displacement.
My car is about 140k miles now
i corcerned little bit cause not always feed her premium gasoline.
it's pretty more expensive than normal gasoline here in Korea.
Thank you for the advice and nice video.
@@user-nu6ro6fu1x To be honest, 80% of time I also use regular gas. However, I add few ounces of fuel injector cleaner every 1K miles just before fill up. When carbo builds up, you’ll notice sluggish acceleration and poor fuel economy. You can also try using Seafoam spray every 10K miles through the intake and that’ll remove some carbon in intake and piston heads. At 150K, if you haven’t, it’s due for spark plug change. Only use exact OEM. The most I worry about is not having done transmission fluid change. I’m at 119K miles, so I’ll be doing this in the spring.
@@user-nu6ro6fu1x BTW, I’m a long time Korean-American immigrant.
@DIY & Life Skills
Well, i never knew you were born in KOREA.(Native speaker i guess)
Actually i served in U.S. ARMY in Korea as a Katusa soldier long-time ago
Now 25 years has passed with no use of foreign language
So i'm poor at English that could not understand everything you told me. But with google translation got it almost.
Before i got the car, the X-onwer had
100K package repaired like plugs and waterpump parts.
I also use gumout and inject cleaners for engine fluid burns.
Those transmission and differential fluids were changed a few months ago.
Alternator was rebuilt too in January
I heard start-motor and compressor would be the next.
Hope i could drive this car 100k miles more with good conditions.
Gs460 is my wish in the future too!
Some of the manifold bolts stripped on me... used speed out bolt extractors. And clips broke on me too... never had that much problems with clips.
On many cars regardless of brand, it seems those plastic connector locking clips become fragile after about 10 years. I think it’s combination plastic material degrading and the clip locking area becomes bit stuck with debris and bit of water and oil vapors to form bit of barrier like if it was glued.
Same goes for rubber hoses, often they become so hard and they do not flex as much and becomes rigid like plastic.
For small bolts, I try to loosen them first manually and then use power tool, because if I use power tool first, sometimes it tends to strip the bolt. For big bolts, they hold up better to power tools.
Where did you get the gaskets for the lower intake valve? can’t find none no where lmk me know asap plzz😢
I got the gaskets from Lexus dealership, but you can get quality gasket replacement from RockAuto or major auto part stores.
Thanks for this. I have the same car. Time to probably get it carbon cleaned 🥴
How many miles do you have? Have you ever cleaned them before?
How much does carbon cleaning usually cost ?
@@TheN4UM4N For this car $1000+. This is very do-able at home as there is no technically hard step. The only challenge is many things you have to disassemble and patiently scraping off the carbon, but they are all straightforward. Do plan for entire weekend of work if this is time doing this. I only regret not having the long pick to complete the cleaning even more.
@@DIYLifeSkills thanks for your reply! I have the 2008 GS350 RWD and I plan on doing this in the near future. Appreciate your videos!
What's up bro I've been meaning to ask you on your video with the ballast replacement what was the actual ballast you used I may have missed it in the video...i do remember you stating the screw holes were a lil off...
I had to return the cheap after market one because it didn’t fit, so I still have the original ballast. It turns out the problem was my HID bulb. The HID light always came on when I start the car, and then it would go on and off as I drive. So I thought the bulb was good and it was the ballast, but in reality it was the bulb that was going out. Apparently, HID bulb just doesn’t go out suddenly. It deteriorates like this. You can see the picture of the salt inside the HID bulb bulging in the video. After I replaced the bulb with the matching OEM one, light stays on all the time and doesn’t flicker on and off now.
Also I’ve read many having trouble with the cheap after market ballast going out within a year. If you must replace it, I would go with used OEM one from a later model year, but before you do that, test the bulb. It’s more likely the bulb is going out.
What symptoms are you experiencing?
@@DIYLifeSkills they are completely off
So the ballast from a 01-05 would work
@@eugeneowens82 I'm assuming just one side of the HID light is off? Did you try to swap bulbs just to make sure that it's not the bulb? It's a lot of work to remove the ballast.
i have the same lexus check engine vsc light traction control ON any idea what it could be ?
Could be many things. Did you check the ODB code? If not, auto part store can read the codes for you. There could be more than one code, so get all the codes.
@@DIYLifeSkills P0500 vehicle speed sensor A . my car does no shift higher than 4th gear
@@giovannicarrillo9245 This is a tough one because of generic error code. Many have replaced the sensor but still getting P0500. The issue could be trans, ECM, bad wiring connector some where, etc. You may have to get Lexus to diagnose it.
@@DIYLifeSkills i`ll definitely take a look tomorrow . thanks a lot sir 👍
Wheel bearing for the traction control
Absolutely detailed. I just finished one. And it’s completely the same. Just want to know the name of the two wire sensor on the back of the lower intake manifold.. went to Lexus of Torrance. And the department could not identify the part. I still was able to get a new connector for $15. But it’s listed simply as. “Housing”. No pins included.. so I’ll have to remove the old ones. Possibly solder old wires and insert
Thanks for the feedback, and I'm not surprised that many parts have same generic name but with different part #. LOL
Great video! I believe I have a bad injector in my ‘06, so this will come in handy! Also, noticed the Well-Pict box. Are you local to Watsonville?
Those boxes are from local Costco in Houston. :-)
BTW, I’ve been using Lucas fuel injector cleaner on all my cars for many years and so far I’ve not had any fuel injector issue. I usually buy the gallon jug from Walmart cause it’s cheaper that way, and put it gas tank before fill-up every few months.
Ahh, makes sense. I happen to live near that farm. lol Thanks for the reply. I usually use Techron or Lucas, but I just bought the car with the preexisting issue. I’ve eliminated the coil and plug as the issue (P0304)), so I believe all that’s left is the injector. Probably explains why I was able to buy the car so cheap. lol
How many miles and what did you pay? This video will get you almost to the fuel injectors. If you do this take things apart, you light as well clean the intake valve carbon build up since 06 is GDI engine and I’m 99% sure you have heavy carbon build up.
185k, $2800. I ran a couple of cans of Lucas GDI cleaner through it last week, but will definitely do more cleaning once everything else is exposed. Thanks again.
@@mikeself wow amazing price. I would’ve bought it.
Where is the SCV MOTOR LOCATED ON THE INTAKE MANIFOLD?
I’ve never heard of SCV motor. What does SCV stand for?
Shesssss💯
Do you know Where starter is?
On the lower driver side of the engine.
You can also find UA-cam videos on how to replace it. Mine still good so I didn’t have to do it yet. How many miles do you have and what year is it?
@@DIYLifeSkills some videos shows the starter can be taken out from underneath the car, but I could not find it by looking up from the ground. So I followed the manual to take parts out from the top. After took the lower intake manifold off, I still can not find it and end up with cleaning only then put everything back. Mine is 2006 gs300 AWD 3.0L engine with 296k Miles
@@MeoConCon Wow you have nearly 3 times the mileage compared to my 2006 RWD GS300. You should’ve been able to follow the positive battery cable, which is connected to starter. And starter gear engages flywheel if engine. I’ll check mine after work today and let you know.
@@DIYLifeSkills I finally found it. you’re right, it on driver side but hidden under left side engine. taken off lower intake manifold is just a haft way to get there. well it is a hard way to excess from the top. but if goes from the ground up, still need to unbolt engine mount, left axle, left sub frame…. to open space to take it out. gs300 is a nice car but so stupid design for starter location 😏
The back manifold bolt killing Mih as we speak
It requires deep reach but the bolt comes off easily once you figure out the body posture to reach in there.
I got it smdfh when u high u like at sum type low level strength 🤣 when I got stuck a auto store lol in da hood I had super strength and adrenaline rush lol them bolts hand tight torque
Like u Said Angle reach every thing
Then I break air switch hose at top lol 😂 another $40 dollar part , cause how hose broke off
Lol! And they say Lexus makes well made cars.
