[@rl7880]

Wow! I'm so glad I found you again. Viktor, your knowledge and videos are so helpful. You really are saving so many of us hundreds if not thousands of dollars of the course of ownership. Many thanks.

[@Viktor_G_Automotive]

Thank you for the feedback!

Great suggestion!

I own a 2018 RX450H F Sport, and I've noticed that no one has demonstrated how to change the spark plugs on the 2GR-FEX engine. I realize there are 20 RX350's for every 1 RX450H, and the numbers are even greater if the Hybrid model is an F Sport. Can you perform a tuneup on a vehicle such as mine or is it so similar to the RX350 that you and everyone else don't bother?

[@Viktor_G_Automotive]

It’s similar to an RX350, but there is more work involved. There is an EGR cooler that has to be removed to access the rear plugs. I may make a video one day, but there are a lot less hybrid models out there to get my hands on one.

Hey Viktor, I'm planning on cleaning the throttle body on my 2014 Lexus IS 350. Is it fine to move the throttle body plate by hand? Thanks

[@Viktor_G_Automotive]

Yes, that’s totally fine.

[@JasonSD619]

Thanks for reuploading your videos! Can you please make a video on changing sway arm bushings for a 2017 RX350? Thanks in advance

[@Viktor_G_Automotive]

Will do when I get a chance, thanks!

Hi, Viktor. I have a 2015 NX200t with an 8AR-FTS engine. Recently I found that the idle speed in D gear will be unstable when stopped. So I'm not sure if it's because the throttle body is dirty and needs cleaning. However, I checked the relevant information online and found no information on how to clean the throttle body of this engine. So, do you have any other suggestions? Thank you.

[@Viktor_G_Automotive]

The idle speed is computer controlled. You can try to clean the throttle body, but it is not easily accessible. There is not much else to do, if the idle speed varies slightly, it is not usually a cause for concern.

Can you post how to replace the thermostat and water pump on a 2022 Lexus RX450h hybrid (2GR-FXS) please?

[@Viktor_G_Automotive]

Will do if I get a chance

[@linroy3223]

Thanks for sharing. I thought the electronic-controlled throttle can’t be handed push to open the valve, can it? Can you teach us how to relearn the idle after cleaning the throttle? Thank you.

[@Viktor_G_Automotive]

Hi, you can definitely push it open by hand with no issues. Idle is learned automatically after a few drive cycles. Thanks for watching!

[@jennypreston9755]

Can you show on the 2012 gen rx? I can clean the throttle body easily on the second gen, but haven’t figured out how to on the 3rd. Same with the mass air flow sensor. 😢

[@Viktor_G_Automotive]

Will do when I get a chance.

Hi Victor. I’m experiencing a few issues with my 2017 Lexus RX 350 fsport. I experienced 2nd engaged, 4wd, ICS and engine light on the dash first and then stalling at red light. After I filled up I drove a mile and it stalled. Took it to the dealer and they said I need to replace all 12 injectors direct and port. I don’t believe all 12 are bad. The codes the gave me was P0172, P0175, P0117. Which points to multiple sensors. Can you point me in the right direction?

[@Viktor_G_Automotive]

Unfortunately, it’s impossible to diagnose without me being there looking at the vehicle and running a bunch of tests. I do agree that it won’t be all 12 injectors, most likely only one or two. There is a way to test if it’s the port or direct ones causing the issue, but it can be very difficult to confirm which specific one.

[@chuckpar2206]

Viktor, thanks for the video. Question about a 2010 RX350, any possible issues in pushing the TB plate open by hand to facilitate cleaning? I read you can damage the TB electronics?

[@Viktor_G_Automotive]

No, nothing will get damaged. That’s the only way to clean then.

[@chuckpar2206]

Thank you

[@Viktor_G_Automotive]

@@chuckpar2206 no problem

[@chuckpar2206]

@@Viktor_G_Automotive Thanks again Viktor. I purchased a twin pack CRC TB and MAF sensor cleaner. I'll clean both components, since I would have gone that far in disassembly following your instructions. Seems like a good time to spray clean the MAF as well.

[@Viktor_G_Automotive]

@@chuckpar2206 sounds like a plan 👍

[@user-nn6sq8ow5g]

Are the instructions the same for a 2022 Lexus RX450h hybrid?

[@Viktor_G_Automotive]

It’s harder to get to the throttle body on a hybrid RX, but generally speaking it is a similar job.
