With the key on the “on” position u can have someone step on the accelerator to open the butterfly or wedge a stick or something between the gas pedal and seat to keep the butterfly open. Then you will be able to clean the throttle body without manually pushing open the butterfly which is not recommended
Thanks for some advies.I will try tomorrow but my FX35 does not start with warm engine at all.Only when I cool( wait) for a 20-25 min to cool down ...I,ll let you know😀
Hi, I have FX35 2006 model, the car does not go over 4000 rpm / 100 miles per hour, with gas pedal fully pressed. Car has 140.000 miles on the clock. I took it to diagnostics, no fault is shown. Could this problem be related to MAF and throttle body?
I have a 2007 Z , i live in Florida , heat soak is a problem in the summer , you still have the CCV’s hooked up to your intake air tubes , this is where your getting all that dirty stuff from , and the hard starting in the summer , it can’t come through the air cleaner , so out of the engine it comes as an oil mist , unbrunt stuff sucked right back into your intake system , causing all that stuff you just cleaned , don’t let your engine recycle that dirty air back into its self , vent it into the air under the hood
do we really need to disconnect the throttle body, or can we just spray in there without taking the throttle body off? those 4 screws look like a bit of a headache to take off...
I have done mine several times without taking the throttle body off. I will do it again very soon, removed, as it is a more complete clean. Thanks @TheRealMeCoWhy !
I have a 2008 ex35 that gets stuck in third gear when it gets hot. Transmission specialist said I need to replace the throttle body for over $3,000 Do you think cleaning the throttle bodies will fix the problem?
Great video content.. by any chance dud you change any sensors. I am trying to locate the crankshaft position sensor and transmission speed sensor apparently the 2010 is different than early years which videos aren't helpful
Yes! He missed that step. However, you also DON'T need to remove the throttle body from the housing to clean these. You can hold open the butterfly with a finger, spray the fluid, then use a rag (not a napkin/paper-based product) to clean the plate and tube. I prefer to remove the tube entirely and spray that down w/ the MAF sensor in place, there is no need to remove it. I replaced my rubber gasket at 50K and 100k miles just because. NOTE 1: The throttle bodies on this video are very dirty, I'm guessing they haven't been cleaned in some time thus the problems, if you proactively maintain your vehicle you wont have these problems. I perform my K&N filter, cabin air filter and throttle body/MAF sensor cleaning every 15K miles. NOTE 2: There is a different cleaner for the MAF sensor and the throttle body.
@Michael Barker Have you not seen the amount goo that came out? You must remove the throttle bodies, you don't want that greasy goo going down your engine.
Just did the plugs today not that bad to replace the spark plugs I didnt completely remove the manifold just certain hoses and moved the manifold around just enough to get to the rear coil packs
Doo not doo this when cleaning your throttle body... put the car in Acc put it in Drive press the gas the throttle will open then clean it... Doo NOT push the butterfly with your fingers.. But if you think im just talking craziness say hii to the Stealership$$$
Otherworldly Burrows I’m pretty sure you should not even touch the butterfly of the VQ engine. If you do, you will likely have to do the idle relearn procedure. These throttle bodies are quite sensitive. You might get away with it, but there’s a chance adjustments will be needed.
Thank you for the video. I used the procedure to clean the throttle body. I moved the butterfly. Can someone point me to the idle reset/relearn process?
@@@TheRealMeCoWhy Yes. It does. Idles at 1500rpm. I found a process by @Motordyne G35. I think I'll try it unless you recommend an FX35 specific process. Thank you.
Do you know if this is the same for an ex35? (it is a 3.5l engine) I have a 2008 and it starts and stalls when it is warm. Never cold and I can usually get it started about the fourth time. I have a new starter and alternator and it has not fixed the issue.@@TheRealMeCoWhy
Great video him big help also let me ask you what a bout map sensor is on that vehicle where is it located and does it have one less a 2010 Infiniti G 37 sedan thanks?
The MAF sensor cleaner is a non-residual type cleaner, not quite de-natured alcohol but something like it. 3M make one. A bit costly for the spray can, but it's something that should be cleaned done 6 months to a year so you will use it, and on all modern cars. The reason is the MAF sensors get coated with diesel combustion residue on the street and other similar things and dust, then give poor readings on air-flow, and the car will run lean or rich, probably lean, which is bad news.
Just wanted to say thanks, I cleaned my MAF sensor today and my hesitation is gone now.
I'll try that also. Has a new air filter so that's not the issue, otherwise I'll look at the throttle-body. J32.

Did you have to reset the throttle after you moved the butterfly?
Great video! Also beautiful music in the background.

Did you disconnect the negative battery terminal before starting removals?

I'm replacing both my Throttle Bodies... Do you know how much coolant is expected to leak out the hoses when i disconnect it from the TB?
Do I have to do any reprogramming for them after cleaning? If yes how do I do it plz!
No need for reprogramming. Do NOT disconnect the throttle body and do NOT disconnect the battery. You should be good.
Yes
Yo

Would it’s throw a check engine light on?? P00174?
Did you disconnect the throttle body?
Yeah thanks the video but I'm scared to twist the butterfly inside the trotle body
Battery don’t need to be disconnected? Recalibration is not needed after cleaning?
do we really need to disconnect the throttle body, or can we just spray in there without taking the throttle body off? those 4 screws look like a bit of a headache to take off...

U need a right angle adapter for the impact gun.
where did you get that music from

Thanks for the video. Do you know where the MAP (manifold absolute pressure) sensor is located on an FX50?
Really good video thanks.
After moving butterfly you will need to complete an idle relearn procedure
Mikolaj Stachura OK good, seems not disconnecting the battery is the trick
Not the battery to be precise. He didn't unplug the throttle body connector, otherwise it will be a must.
Personally I would prefer the reset/relearn.
@@micgeneva998 I have a G3.7x Can you please tell me how to Reset/Relearn process
Good time to replace air filter while you are in there..
make a video about spark plugs
Just did the plugs today not that bad to replace the spark plugs I didnt completely remove the manifold just certain hoses and moved the manifold around just enough to get to the rear coil packs
Thanks for the video. I'll do this on my own now. If throttle body is dirty the intake must be too. Should the intake be cleaned? How?
I would only do the throttle body.
MeCoWhy? Thanks.
Yes, clean the the tube AND the MAF sensor at the same time...use different cleaners for each.
Doo not doo this when cleaning your throttle body... put the car in Acc put it in Drive press the gas the throttle will open then clean it... Doo NOT push the butterfly with your fingers.. But if you think im just talking craziness say hii to the Stealership$$$
What should we do then?
Not true on the g37. Pushing them open does not damage anything on the g37s. I agree in some cars it does. But not the g37. No harm at all.

+1
What about disconnecting the battery first, so the sensor doesn't detect the change.
You just had the key off? Battery still connected?
Yes. Car off, battery connected.
must be the same process for a Qx50 3.7
Was it the same process I have a 2016 qx50 3.7 and my fricken car is like not wanting to shift out of 2-3rd gear the RPMS rev high
Thank you for the video. I used the procedure to clean the throttle body. I moved the butterfly. Can someone point me to the idle reset/relearn process?
Does the car require the re-learn at this point? Did you disconnect the throttle body at any point?
@@@TheRealMeCoWhy Yes. It does. Idles at 1500rpm. I found a process by @Motordyne G35. I think I'll try it unless you recommend an FX35 specific process. Thank you.
@@h94403 I didn't have to reset the idle on mine. I would try the process you are refering to. If it is gen 2 G35, it is the same motor.

@@sharikumiega8186 I am almost certain that's the issue.
Great video him big help also let me ask you what a bout map sensor is on that vehicle where is it located and does it have one less a 2010 Infiniti G 37 sedan thanks?
Not sure about g37, but these engines are similar so it should be in similar location as in my video.
Same location, there are two of them, one on each intake. Clean them with MAF cleaner, not throttle body cleaner.
So you used the same spray to clean both the MAF sensors and the throttle bodies?
Each has a specific cleaner, can be found at any auto store
He did, you shouldn't. There is a different spray for both.
The MAF sensor cleaner is a non-residual type cleaner, not quite de-natured alcohol but something like it. 3M make one. A bit costly for the spray can, but it's something that should be cleaned done 6 months to a year so you will use it, and on all modern cars.
