This is how far diy videos should be man, thanks! I’ll try this out when I get time to!
This is the first time I’m commenting on UA-cam. Feel like it’s well deserved. Thanks for this vid bro!!
Enjoyed the video. You are well spoken, clear and concise. My dealer told me to replace and not clean mine.
Same thing with me. I was told to replace the throttle body on my G37 and the labor alone was 2k. Their nuts
Love that there aren’t a million cuts in this. Makes it feel more whole.
Times have changed bro... glad to see where you started n where u are now... thus came in hand... thanks
Nice job! Keep the videos coming, my G37 runs great and I plan on keeping it that way.
Thank you!! Another video headed your way shortly! Enjoy!
Thanks for the video you saved me a lot of time and money. Looking forward to other video on infinity.
Great video. I'm tuning up my brother in law's 2010 G37 sedan this weekend. This will be part of the process. Thanks again.
Great DIY video! Keep them coming
200k miles thats a beautiful sight i have 185k on my v36 g35s 6mt. Great cars man
Great Vid!!! Missing having you across the street.
Benjamin Rapp ha! Thank you, sir! I’m sure it’s a good and bad thing I’m not there anymore 😂. No more loud exhausts for you!
Have any new projects you’re working on?
Awsome video man the most helpful I’ve found
Thanks so much!!! So glad I found this video!!
Thanks for the video was having the same issues on my 2020 Q50
Best video ive seen about the throttle body cleaning ! Keep it up brother! Ill be cleaning mine myself as well instead of going to a shop and be charged way more than having some of those tools since we all need them anyways ! Thank you !
Esta that's great work par🤙
Yes this is exactly what’s going on with my infinity thank you
Same i think but i’ll just buy throttle body cleaning fluid and try it today. How was yours?
@@ImBadNewz I don’t think it actually Has to be auto throttlebody cleaner
@@kevinsnell5031 too scared to try, just replacing stock intake filters with hot air ram k&n ones for now lol
Thank you! Helped immensely
Hey bro, been following since you posted on the G forum on Facebook. I wanted to suggest to you for next time that if you leave the battery connected and with ignition on you could use a short pole and wedge it between to seat and gas pedal. This will open the butterfly valve all the way open while you clean it and prevent you from having and idle air learn issues once complete. Ive seen and been a victim of the idle relearn process and ended up needing new throttle bodies to fix my issue. Anyways, great video and happy this worked out for you with no issues in the end! Also, blue tooth obdlink lx dongle and Nissan data scan 3 works wonders!
LMCassidy Excellent advise! I hadn’t heard that method before, but makes complete sense!
Thanks for the comment!!
Bring A Trailer Builds no problem. I figured this out on my second attempt and it made it painless and easy.
What cleaner do you use LMCassidy
Gonna try Bring trailors method today
Wow so smart gonna do this today
Helped me get better response and better mpg!!
Absolutely! And it’s pretty simple to get good returns!
W vid bro I can’t believe I was about to pay a shop to do this bs for me 😂 thanks for taking you time and explaining everything 👍🏽
I dont have an Infiniti but a 2009 Nissan Murano. P0507 and p0174. My rpm is currently sitting at 900-1000 while in drive. At idle rpm fluctuates between 1000-1200. No power issues while driving Highway speed. Performed the IAC Relearn procedure but to no avail. Will keep diagnosing.
What happened man I have the same code trying to find the problem before I put mod money into it
Nice video bro, thanks
Here before the first Million 🤙
DONT USE BRAKE CLEANER. USE THROTTLE BODY CLEANER!
Same thing
They both provide the same function, and carry the same results. Don’t be a fool…
Just marketing, same shiiittt
U mad bro?
Whatever you say ❤❤❤
Brother thank you sooooo much for this video.... this was def something i didnt know and it helped alot... god bless...
Thanks man !
Thank you
Hello, i have recently installed ported upper and lower intake manifold before and after tune the engine has rough idle I did ETB relearn but it keeps stuck at 1100rpm, my throttle body is clean but i suspect the vacuum lines, so how many PCV lines in VQ37VHR platform
I know this video is old but wanted to ask. If I disconnect the negative ground on the battery will I still need to do a relearn after I'm done? I heard that if you disconnect the battery you don't have to do relearn. Do you know if this is true?
I have 2011 G37 did that to it also cleaned the sensors too holy fuck my car got way faster and more responsive now i think that my car was choking 😅 haha thank you bro for the video
Thanks
My Baby I Miss Her 🥺✊🏾
The backside of the Throttle bodies is actually what's dirty. I cleaned mine I don't think it's stalled since but my rpm still fluctuates a little at idel.
Try doing an idle air relearn.
Do you personally clean parts for your customers or is it just for this platform? Are you located in LA ?
no issue with brake cleaner on the rubber hose? :) thanks
while i was doing throttle body cleaning , notice pvc vavle nipple broke off in hose , how d ii get pvc out of valve cover
If you unplug them it can cause issues right?
Hello the Infiniti fx50 2010 how can you fish the throttle valve?
Did you unplug battery beforehand?
Do you disconnect the battery when you clean the throttle?
yea just remove the negative terminal, with out disconnecting the battery the computer will still think its dirty since its adapted to the dirty condition... it needs to relearn the new clean condition...
Not the hart palpitation when you almost lost your bit 😂
I was told to only use throttle cleaner, especially on newer cars such as these !
Not a bad idea. Fortunately we’re cleaning post-mass air flow meter so there’s no sensor to damage in the process.
Best practice to use throttle body cleaner though. 👍
Did all the cleaning and still my car is in limp mode, left the car sat for just a week and it revs slowly in every gear and will only go to 55mph any ideas what's going on??
Is supposed to be around 500 rpms or 800 rpms ?
Would it hurt the car if you disconnected the wiring attached to the throttle body?
I think if you disconnect it you would need to do an idle relearn on it
Does the same relearn work for the 2014 q50 with the 3.7?
Infiniti was about to charge me 259 for this exact same thing and cleaning MAF lol goof thing i saw this
I have a 2012 infiniti g37 it was working very well and suddenly it just turns on and off. What recommendations would you give me
What was it ... u fix it??
Nice video bro… For the future never ever ever ever touch those butterfly valves.
You can touch those butterfly vavles inside the throttle body? Its totaly fine you just cant be rough with them and let them shut when you close gotta close slowly 😊
How come
Because there is a tiny gear inside that holds them close. You can skip that gear back a tooth or two, and then the "re-learn" process is a pain in the butt! Instead just hit it with the throttle body cleaner *while in accessory mode* and then switch off. Do this 3 or 4 times at least. Spray the butterflies -with the pressure of the spray being the only force hitting those flaps. You'll notice after several sprays, the pressure of the spray alone finally opens the flap. Woohoo!
the only thing i could recommend here is that when you spray any sort of cleaner, don’t let it drip onto the components, instead try to put a rag wherever to collect the drips, run off or overflow etc….
What kind of cleaner do you use ?
Same method for a Q50 I’m assuming ?
Great video. So i did this and still stalls once warmed up and you go to put it in d or r it dies if not it stalls at a red light. Any thoughts?
Cam sensor or Maf (mass air flow )
@@iDkwHatToNaMeThIS12 thanks but it ended up being my torque converter locking up.
@@runemproduction3187 it would only turn off by itself at a stop? Would it act rough when shifting or anything else?
Will this relearn work for 2007 Infiniti g35X
Does this cause the p006a code or do u know how sir
I get a service engine soon light and I checked it out it says replace map sensor , and it also says fuel system bank to lean . I was thinking about just cleaning everything out and see what happens
What happened I got the same system bank lean code
Do you do the same process for the q50 as well?
Did u figure out bro
Did you disconnect batter before doin cleaning throttle bodies ?
I would remove the negative terminal, with out disconnecting the battery the computer will still think its dirty since its adapted to the dirty condition... it needs to relearn the new clean condition...
@@cameron2849 so are you saying it’ll automatically adjust or relearn after this is done?
My g just starting acting up it was running smooth before now my gas pedal slightly vibrates and the car feels like it wants to jerk foward when I’m coming to a stop. The exhaust also sounds way throatier than before and like it doesn’t want to accelerate. Do you think it could be the throttle bodies that need to be cleaned? Thinking about doing this tomorrow morning because I’m sick of it running like shit. Anyone have any thoughts? Thanks
Any update?
Update
Update
These cars tend to crack the right air intake boot, just before the throttle body. This screws up the air/fuel mixture. Think it’s probably due to torque twisting of the motor. Think a check of both motor mounts might be in order.
@@drjimjam1112this is well said 💯
Hmmm my G37 has been not starting upon start up after I’ve been driving it around. I’m narrowing it down to the throttle bodies about to fail soon. I’m going to try this.
Was that the problem bro ? I’m having the same problem
@@agentcatalan8454 I haven’t done anything yet, I’m on the fence of getting new throttle bodies or just cleaning the throttle bodies and doing the relearn
@@zabllen I just did my throttle bodies and maf sensors still same thing I’m convinced it’s my spark plugs I feel like they are wet, I just ordered some today when I get them on I’ll let you know.
@@agentcatalan8454 do you have any codes? And does it cut off and usually come back on if you try and start it again?
@@zabllen on cold starts it starts up really well but when I drive it and let it sit for about 30 mins it hesitates to crank almost sounds like if it was the battery but I have had a couple times where it fully didn’t crank after driving it and I had to crank it up again. I checked the battery which was good I just did my throttle bodies and maf sensors still same thing. I’m narrowing it down little by little that’s what I hope so
Will this work on 2015 q50 3.7
How often do you have to do this.
I checked mine, it like like that. Maybe a bit more dirty.
How much does the valve open when idling?
Does this work for throttle lag when I drive it like lags weird hesitates the car jumps back and fourth lol and goes away some times really weird I have a 2009 g37 sedan 6 speed I hate the problem worries me no check engine or anything I’m gonna have my mechanic clean my throttle bodies hopefully it goes away
any update on this? im starting to have the same issue lol
@@justinblas7814 it goes away when you let the car warm up 5-10 minutes before driving it
@@Ohhoneangel but did your mechanic clean up job work?
Today for the first time after 2 years of owning my 2017 370z, it would start and die almost immediately after. It would run perfectly once fully on but I would have to rev it to start. I'm really hoping this will fix it 🙏
Any update?
@@zabllen fortunately it hasn't happened again since the original time. I'm glad its gone but I would still really like to know why it was acting up. Also, I never touched anything since it happened, it just went away.
Same thing happening to me rn trying to figure it out 🧐🧐
@@michaelbrocco1995 mine also. 2014 automatic. I’m going to clean the throttle body and see if that works
@@MF007 Did it work?
Is this the same on a Q50?
tried replacing my spark plugs and took a break when i couldn’t get the bottom right bolt on the throttle body. put everything back bud now it’s in limp mode with check engine light
did you fix it?
what was the issue
@@DerzFlash my dumbass didn’t plug one of the MAF sensors in all the way😭
So u don't have to unplug the the throttle body??
Cool. How many miles did yours have at the time of this service, & at what mileage would you check it?
Ok as I watch I now see damn near 200K on the odo! Wowza! I have a 2013 with only 65k... but at one time my throttle was acting sluggish. It has since gotten better on it's own, but was wondering if this was a job I should do...
Same steps for a q50 with a 3.7 at the end?
Yep! Same engine.
I’ve seen and heard people talk about BE CAREFUL WITH THE BUTTERFLY 🤔
Would relearn work on ex37?
I did the same steps, then my throttle hose cracked. The part is drive side around $260 and passenger side around $270.
Never move ur throttle with hands better to do that ignition on and ask someone to press the gas pedal. And while cleaning don’t push the butterfly please be careful very sensitive.
Around $100 used on ebad, also silicone hoses $90 for the pair.
How do u get the infinty out of limp mode,,,car starts but has no power,,,throttle body cleaning???
Did you ever get your vehicle out of limp mode? I am going through the same issue!
@@naeh799 yes i did,,,you might not believe it but the problem was i added about a half quart of tranny fluid too much,,,once we got it to the proper level,,,it ran & continues to run great,,,that's all we did,,,
Just an added note to the limp mode issue,,, it wasn't an immediate problem ( limp mode),,, it seemed to take some weeks to create the problem,,,i replaced the gas pedal,,,wasted $ 300.00,,, we also cleaned throttle bodies,, with the proper cleaner,,,spray it on a rag & wipe,,,don't spray into the body,, good luck?¿?
@anthonygomez3241 So after cleaning the Throttle Body ...what was the Outcome then? Was your vehicle drivable
@@naeh799 no,,, after cleaning it, it didn't help,,,only after the tranny fluid level was fixed,,, souds strange but that's a fact jack...
Did you change out the oil gallery gasket? 200K is the highest mileage I have seen posted.
They changed the gallery gasket if it’s post 2012 and didn’t experience as many problems
I have 235k on my 08 g35
I had a g35 that hit 330k
I know your car is Infiniti but mine is 370z , is the same process ?
The throttle body bolts have an order they should be removed and re-installed; as well as a torque spec.
How to get it out of limp mode
Wish me luck bro I am doing This tomorrow 😞
How clean egr valve
Are you in ga
It’s actually not a T-5 hex, that’s to small of a bit. I used a s5
Should the battery be disconnected? For this?
I didn’t disconnect the battery. Probably best practice to disconnect, but I don’t think it’s imperative. Just make sure you don’t unplug them.
Disconnect the battery before performing this job, that way you don't have to reprogram
So disconnecting the battery u don't have to relearn? I didn't know that
Hey ro idk thaand nowi bave missfirewhat I do now
At least torque them to spec the right way they all have a sequence. Be careful.
Too much work, any other way to clean that without disassembling the throttle
Is the entire video a black screen with just audio?!😐😐
Idle is too high.
No need to disconnect battery to do this job?
