Excellent tip/advice on turning on the lights and pushing horn to discharge all the caps in the system. Not sure how many people realize just because you disconnect power or turn something off doesn't mean the system is discharged. Capacitors don't instantly discharge just because you disconnect power. It can take a while unless you discharge them like you showed.
What about plugging a device into the power outlet ("cigarette lighter" port) such as a phone charger cord and a phone? Most of these things have a pilot light and would show when there is no juice.
@@AnthonyJ350 I know this is an old vid but does this work without doing the reset? And wold it work for a g35 2006 I understand the 350 z and G are basically the exact same i just wanted to be sure.
I got my CCV mounted remotely , using a 3”x2” KN breather , and some 5/8 hose = 15mm , there is only one outlet on my 2007 350Z , there is a space on the left side of the motor in front of the support , behind the air box , so my engine doesn’t suck in any oil mist or hot air from inside the motor , don’t have much build up on the TB’s , but both of mine just went down , did the pedal , also , so i got about $600 , so far in it ,
This is unrelated but today I switched to Shell 5w-40 from Mobil 1 5w-30 and the zed is quieter at 137,000 miles. I cleaned the maf sensor and airbox as well. I've cleaned the TB while it's on the car but never off. Clearly per your vid the TB is thoroughly cleaned when its off. Btw, were you using a torq bit to remove the TB bolts? If so what size.
That's awesome to hear it's smoother, I would post that comment in the Oil Viscosity video we did to show people. I used a Snap-on hex head socket to do the throttle body.
Great video!! I did both of my TB's last year. I do want to bypass the heater hoses going to them soon. I live in a warm climate and don't really need that. Where did you get the cooper plate?

Thanks so much for taking the time to watch our videos! I'll have some more Z content in the next few weeks. Going to start filming a Mishimoto radiator swap video. The fans are on order so I don't know when I'll finish the video though.
Was having a high idle of 1250rpms after cleaning throttle body and maf sensor, took everything apart and tested the operation (recorded with my phone) and my butterfly valve is not responsive at all🤷🏾♂️
Check for vacuum leaks. Is the PCV hose under the intake tube installed properly? Also check the intake tube on the bottom to the throttle body. It might be folded up.

Hey Anthony, how were you able to check the throttle body movement with the pedal? Ignition on(non-start?). I tried with mine(HR engine)and mine to not move, or at least the driver side didn't. But both should move.

Hello Anthony, first of all thank you for the great videos, they are very informative. I have a a question regarding the cleaning of the TBs of an VQ35HR engine. As I have read lots of guys out there are complaining about surging idle and not being able to relearn their idle after cleaning them. Some even say they needed to change the Ecu. So what do you reckon, why is this happening mostly on HRs? And if I strictly do what what you advice in this video ( disconnect the battery, press the honk/discharge the ECU, disconnect and then manually touch the butterfly and clean the TB) will there be any chance of messing things up? My only sign right now is a little bit low idling for a second when I stop at a traffic light. And I want to be sure nothing worse will happen if I proceed with cleaning the TBs. Thank you once again! Cheers!
I'm not sure why HR owners are having this issue. You'll have to go on the forums and ask those people how they cleaned it exactly and compare their procedure to how I performed it in the video.
Good attention to detail...I prefer using Deox-it on the connector then following with Dyelectric grease...You can prevent possible intermittent electrical problems due corrosion by prevention.
I have been using Deox it (100) and Deox it (5) for over 20years in professional electronics Calibration and repair laboratories...I have fixed hundreds pieces of test equipment by solely cleaning connections ...Corrosion/Tarnish can reape havoc on connections...As a long standing practice, any connector unplugged will be cleaned with Deox-it and further protected against the elements with Dyelectric grease.
I may try this when i get off work. This morning my car decided to shit on me as soon as i left my house. Wouldn't go past 2800 rpm when accelerated. Im going to try and clean or replace my MAF sensor first and then go from there.
I would love to talk to you! Hope we can hook up! What happens if a relearn is not done? my nIssan Murano 2011 fuel injection and throttle body cleaned in 2019,. They did not relearn that I know of. Did have a code P0101 that came up within a month or 2. Other mechanic place said was a "torn boot" and replaced. In 8/21, Nissan dealer "cleaned the throttle body". Manager would require a relearn. None done. Car has had issues since end of May when they had it for 90K. The P01010 code came up. they replaced the MAF sensor and charge $$340, and also the VIAS ASSY. My husband brought it hopme. I wanted to see the assessment. There was NONE! Still has issues. took in again in August. They cleaned throttle body, no relearn etc in May or August. starting issues, now coolant low, not sure what else. Daughter has it at school. Also AC doesn't work since July.
You can try doing the relearn yourself th-cam.com/video/5tQm28K32SQ/w-d-xo.html Seems like an awful lot of problems. You can email me at info@gofasthavefun.ca if you have other concerns and I can try to help out.
I did this, now my throttle pedal lags when I let off the gas, i think the throttle body might be getting stuck open. My mechanic said it was dumb to touch the butterfly but I cleaned it a lot better if I hadn’t and it starts runs and idles a lot better. Only problem is the pedal lag and I’m not sure how to fix it, maybe take it out and try to see any problems? Any advice lmk please.
I’ve been watching your videos a lot now that I’m doing maintenance on my 350z , Quick question maybe a bit ignorant but why is necessary to reset the ecu , after cleaning the throttle body?~ thanks.
Hey man. I love the setup. Those TB sensors are known to cause no start symptoms when the circuit has a voltage problem and the unit needs to be replaced. The good thing is you'll get a code right away. For some reason the Starter or fuel pump- No codes. Thanks for the maintenance tips.
Hey man I have an 03 350z and I have a similar throttle body spacer, i have the code p0507 and its causing me to lose power/bog out at 3.5k-4k rpms. I tried everything, tried the relearn 100 times, tried new throttle body, tried new maf sensor, nothing is fixing it, pleeeeease help me
Has the car ever stalled? Cam and crank position sensors all seem to be failing now that the cars are older. I have videos on those parts if you want to check it out.
AnthonyJ350 car doesn’t stall unless I try to do a burnout, at around 3.5 to 4k rpm car cuts power and just revs super high, bogs out badly, thinking I need a new ecu? I’m 19 man I don’t have much money my dream is to rocketbunny it and eventually make it into a track build but i just spent all my money trying to get a shop to diagnose it and they couldn’t even figure it out
AnthonyJ350 they did a smoke test and found a large evap leak, fixed that assuming it would fix my issue but it didn’t, still throwing the p0507 code, and yes I’ve tried that relearn, I’ve tried every relearn procedure for nissans pretty much
Hows your throttle body working after your move the butterfly that will definitely be damage is you touch the butterfly in the throttle body it so sensitive it will mess it up !
Some videon on here says that you are not supoose to touch the the plate in the middle with your finger cs you could damage the throttle body. I have done it the way you did it and i have not had a problem with the throttle body
Hey man very helpful video! Do you know by chance if there is a way to reset throttle response? I was wondering if the ECU adapts to your driving style because I have felt my throttle be more sluggish lately. Thanks!
Hey Anthony, I'm installing a new throttle body tomorrow and wanted to know what size is the 4 throttle body bolts? I need to make sure I have the correct tool before going all in. Thanks!
I don't remember off hand. You'll want to buy a set of metric ball head allen sockets that are longer. Kind of like this www.canadiantire.ca/en/pdp/maximum-long-arm-ball-end-hex-bit-socket-set-12-pc-0581438p.html
I have a 2003 modle with the VQ35DE and I just cleaned the TB and installed a plenum spacer. I just can't get it to idle normally :( I did all the resets and it seems successful, but the car idles around 1100 rpm and when I'm revving it it will drop to 1500rpm and hold for a sec and then back to 1100. And if I'm in gear it idles also around 1500rpm.
Can you help me? My car when is hot drives well, but when switched off and left for an hour then started again after a mile of driving when switching gears or braking it can easily shut off. It also can stall when accelerating. It doesn't happen if I wait 3 minutes before driving
@@aeroladen2039 Hey what's up man. From what I call of the issue there was no code being thrown which I hope is the same with you. At worst case from what my mechanic told me I would have to replace one of the throttle bodies but me being me I would replace both at the same time (VQHR here). But in reality all he had to do was spray some of that throttle body cleaner on them and that was it. WITHOUT touching your throttle body take a flashlight to see if it is dirty. If it is dirty that cleaner should do the trick. Whether or not you will have to do the relearn trick with the throttle body I am not sure. I did not. Just whatever you do, do not touch the butterfly inside. If that does not work. Try doing the re-learn trick. Now if that does not work you may need a new one. I just looked at Z1 Motorsports and they are having a sale on the one for the VQDE. Instead of 369.99 it is 275.99 for the Z1 brand. For 509.99 you can get that, the oversized Z1 silcone elbow and Z1 VQDE plenum spacer kit. Just fyi.
i change my spark plug and clean my intake and now my throttle wont open, i start it then die after 3-5 sec, i noticed i step my gas pedal and my TB wont open , help please? @anthonyJ350
does everything in this video as far as cleaning the carb and electrical connection? also what about removing the two screws holding the butterfly door to make cleaning the body and door easier but also more thorough?
@@AnthonyJ350 a catch can was the first thing I did when I got my Z for the soul purpose of keeping the air as clean as possible as well as the upper and lower. The first Z I had, I ended up removing the plenum and seen just how nasty they get (got it with 164k miles)
hi Anthony, may i ask you a question about VQ35HR? i cleaned TB and did relearn step many times, but i did not work, idle still at 2K, could you give me some advise for this problem? Thank you!
@@AnthonyJ350Hi Anthony, finally, i fixed it. i tried many times and it was still at 2k, it seems some place has other problem, I found there was a place where is air escaping from the pipe. Thank you so much! take care.
@@AnthonyJ350 in theory it should increase top end since it tapers from 75mm to 70mm instead of the 70mm stock . It is an increase of airflow that should hurt too Hot but help on too end . Would make a killer video and dyno comparison. It's $330 at Z1 on sale . I would get the Z1 brand since it's one piece with 2 solid gasket's instead of the others that need 3 O rings . I mean 5mm it's 5mm of airflow . Can't argue with that .
I got the P0171 system too lean bank 1 code. Could this be my issue? I did my own valve cover and gasket replacement and when I put everything back, that’s what happened. It sounds like a hissing noise from the back as if sir was escaping. My throttle body is a bit dirty but I was wondering cleaning it and replacing the gasket could solve the issue?
@@AnthonyJ350 actually I took out out my upper plenum to realize that it was the gasket. Somehow the back it was all folded in half (rookie mistake) and now she’s running pretty much good. She does idle around 900-1000 but I’m assuming that’s because I cleaned my throttle body and needs the relearn.

I just can't get it to idle normally :( I did all the resets and it seems successful, but the car idles around 1100 rpm and when I'm revving it it will drop to 1500rpm and hold for a sec and then back to 1100. And if I'm in gear it idles also around 1500rpm.
For context I think It's the first time Its even been cleaned for ~140k miles. It was filthy!
Try this and take it for a good drive th-cam.com/video/5tQm28K32SQ/w-d-xo.html
Given the age of the vehicle I would install new cam position sensors and a new crank position sensor as well. I have videos on both.
@@AnthonyJ350 Thanks man, love your videos on the Z
@@botao7274 You're welcome! I'm working on the car again so you'll see new videos on it soon!
Can you help me? My car when is hot drives well, but when switched off and left for an hour then started again after a mile of driving when switching gears or braking it can easily shut off. It also can stall when accelerating. It doesn't happen if I wait 3 minutes before driving
Is there a check engine light on of any kind? What kind of car is it?
@@AnthonyJ350 It's 350z 04'. There is a check engine but cannot read it with any obd2. It came on when driving at highway speed.
@@Grendel817 did you fix it ? Im dealing with same problm now,
do i need a new gasket for the throttle body after taking the old one off?
It's not a bad idea to replace it while you have it opened up.
When I check to see if it mimics me it dosnt move at all
You have ignition on?
If there is a air leak will the car still have a hard time staying on
Depends on the leak I suppose.
Sexy music is very distracting
Thanks for the feedback!
Hey I have a problem with my g35 please help
What's the problem?
Didnt need the porno music, but thx
Are you sure though? I think you should watch it again.
Hey Anthony I have a vqhr that the idle goes below normal rpms then goes back to normal could this be the IAC?
Did you recently work on the car for something?
@@AnthonyJ350 any particular part your referring too or in general?
@@DragoMusivinihave you figured out the issue? I have the same issue.
@@aeroladen2039 Hey what's up man. From what I call of the issue there was no code being thrown which I hope is the same with you. At worst case from what my mechanic told me I would have to replace one of the throttle bodies but me being me I would replace both at the same time (VQHR here). But in reality all he had to do was spray some of that throttle body cleaner on them and that was it. WITHOUT touching your throttle body take a flashlight to see if it is dirty. If it is dirty that cleaner should do the trick. Whether or not you will have to do the relearn trick with the throttle body I am not sure. I did not. Just whatever you do, do not touch the butterfly inside. If that does not work. Try doing the re-learn trick. Now if that does not work you may need a new one. I just looked at Z1 Motorsports and they are having a sale on the one for the VQDE. Instead of 369.99 it is 275.99 for the Z1 brand. For 509.99 you can get that, the oversized Z1 silcone elbow and Z1 VQDE plenum spacer kit. Just fyi.
Should my tb make a sound like if a spring is loose inside when shaken side to side ?
No, I don't think so.
Did you figure out if it was normal or not? My tb sounds like something is rattling inside
Is it safe to do this if my cats are a suspected culprit to a slow but loud ticking
During idle
Should be fine, just removing carbon build up.
i change my spark plug and clean my intake and now my throttle wont open, i start it then die after 3-5 sec, i noticed i step my gas pedal and my TB wont open , help please?
@anthonyJ350
Covering basics, is it plugged all the way in?
You can try the ECU reset procedure th-cam.com/video/5tQm28K32SQ/w-d-xo.html
@@AnthonyJ350 yeah i did plug in all the way
@@AnthonyJ350 i will try it after i work, i let you know if everything works
@@nhikkeyfayloga327 Check all your fuses as well.
What's the size of the allen key used
I don't remember honestly, it was metric though.
does everything in this video as far as cleaning the carb and electrical connection? also what about removing the two screws holding the butterfly door to make cleaning the body and door easier but also more thorough?
I didn't take it apart because I didn't want to disturb the actual unit itself too much.
@@AnthonyJ350 understandable, so you’d suggest against doing that and just follow your video as is
@@codyoneill6091 I would, there has been a lot of success in the comments plus my own vehicle
@@codyoneill6091 th-cam.com/video/iSzU-cvlLO8/w-d-xo.html install an oil catch can to help keep the intake clean
@@AnthonyJ350 a catch can was the first thing I did when I got my Z for the soul purpose of keeping the air as clean as possible as well as the upper and lower. The first Z I had, I ended up removing the plenum and seen just how nasty they get (got it with 164k miles)
hi Anthony, may i ask you a question about VQ35HR? i cleaned TB and did relearn step many times, but i did not work, idle still at 2K, could you give me some advise for this problem? Thank you!
Try disconnecting the battery, hit the horn to discharge the caps and let it sit overnight
@@AnthonyJ350 ok, many thanks for your advise, i will try it later.
@@hunick5538 Let us know how it goes
@@AnthonyJ350 ok, i will.
@@AnthonyJ350Hi Anthony, finally, i fixed it. i tried many times and it was still at 2k, it seems some place has other problem, I found there was a place where is air escaping from the pipe. Thank you so much! take care.
75mm from Z1 bro
Does it actually increase power for the money? The intake manifols opening and the MAF sensor is still the stock diameter.
@@AnthonyJ350 in theory it should increase top end since it tapers from 75mm to 70mm instead of the 70mm stock . It is an increase of airflow that should hurt too Hot but help on too end . Would make a killer video and dyno comparison. It's $330 at Z1 on sale . I would get the Z1 brand since it's one piece with 2 solid gasket's instead of the others that need 3 O rings . I mean 5mm it's 5mm of airflow . Can't argue with that .
Plus you should be able to fit your mishimoto elbow if you do it on boiling water to stretch it out.

Thanks for the comment
I got the P0171 system too lean bank 1 code. Could this be my issue? I did my own valve cover and gasket replacement and when I put everything back, that’s what happened. It sounds like a hissing noise from the back as if sir was escaping. My throttle body is a bit dirty but I was wondering cleaning it and replacing the gasket could solve the issue?
Could possible be a vacuum leak as well.
@@AnthonyJ350 actually I took out out my upper plenum to realize that it was the gasket. Somehow the back it was all folded in half (rookie mistake) and now she’s running pretty much good. She does idle around 900-1000 but I’m assuming that’s because I cleaned my throttle body and needs the relearn.
@@J.Y_Z33 Good job fixing it! Yes perform the relearn after a mod like that.
What kind of rachet is that? My God my friend, get a pear head, people are gonna see this.
Thanks for the feedback!
The multi port fuel injection cleans the back sides of the valves since gasoline is a solvent.
Correct but the throttle body and manifold could possibly use a little periodic cleaning since they're before the fuel delivery point.
