2011 G37, engine light was on, car ran like crap, hooked up my OBD2 reader, had a P0106 error. Watched this video and others. Disconnected the battery before starting, removed and cleaned the two MAF sensors by the bottom clamps on each side. This added less than 5 minutes to the job. I did open and close the butterflies repeatedly with no problems later. Used a small amount of silicone grease to clean the O ring at the throttle body, put it all back together as per this vid. No errors, no engine light, no RPM issues, car runs great. I'll do this again in three years when I change the plugs. Thanks hrkhaliki, you saved me a ton of money.

Just a tip from my own experience.If you cleaning THB you might as well change your spark plugs,or if you changing your SP you should clean THB.Because when you do one or other you must take of THB anyway.

Thanks a lot! 2010 G37, P0106 error. Service guys asked $130 just for diagnostic, but with this video I spent $3 for cleaning liquid, $42 for a set of tools that I wanted to have for a while anyway, and an hour of my free time. :) Important note: just after a cleanup, 'Service Engine Soon' light was still on, but idle RPMs felt from usual ~700 to ~600 (by tachometer, I don't have OBD scanner). The light disappeared after I disconnected negative power cable for ~15 min.

I have an 08 Infiniti G37. I just did the cleaning today 05/15/17. I did everything he said plus disconnect the battery. I figure since now there will be more air flow I figure a hard reset will help it too. I even pushed the butterfly a tad bit to get the grim out from under and top. Everything went well until I turned it on. RPMs jumped to 2500 then slowly went down. She was a bit jumpy on RPMs at first, but nothing crazy since now it's receiving more air flow after removing the carbon build up. I Tapped the gas a bit to get the CPU to acknowledge all this air flow and kept it idle for a bit. I then Shut it down and turned it back on and now it's back to normal sitting under 1000 RPMs. Never had a check engine light or anything. Drove around a bit and she ran fine. Finally, I rev'd high after it was normal and she ran smooth on the highway. No issues on my end. I figure I add my 2 cents to help anyone out.

Omg yo thank you so much I’ve been looking for how to clean it and I finally found your video thank god 💪🏽 Now I’ll clean mines tomorrow

Thanks for the Very comprehensive vid man! Needed this.

thanks man, just cleaned mine and it fixed the flucuating RPM problem and i have a better idle! thanks again

Great video! Well edited...not wasting any time. Appreciate it!

Great video, your instruction is clear and easy to follow.

G37 seems to be very sensitive to carbon in the throttle body. Was having a lot of dead throttle at low RPMs with my o12 G37. Cleaned the throttle body a mass air flow sensors and everything is all back to normal. Never threw any codes.

P0106 is why I’m here. Thanks for the video!

Thank you! I’m planning on doing this when I replaced the spark plugs

I did in my g37x no problem so far.. thanks. ..

When you do clean the throttle body, MAF sensors and replace the sparkplugs, you might want to either clean the pcv valve or replace it since it's in there. PCV doesn't cost that much. That's what I did with my 08G35RWD. Just my 2 cents guys.

ACTUALLY HELPS.. thanks man

Excellent! Nice job.

Good job, I think I can do this myself!!!....changed a map sensor and mass flows today with help from another video, took'er for a nice fast ride down a back road,floated!!!

IT IS ALSO GOOD TO CLEAN THE HOSE OUT AS MUCH AS YOU CAN . GOOD JOB AND THANKS

I had P0106 SES light on 2010 g37x Cleaning TBs seems to clear it. Thanks for the video. Very helpful.

Torque spec is 8.43lb-ft. If it's overtightened or undertightened it can cause an air leak hence you see a lot of people with super fucky idle's after they clean their throttle bodies.

Awesome video, we are going to try and change the spark plugs on my son's g37 and can do the throttle body as well...any chance of doing (or do you know any) videos for changing the plugs- any other things to know... torque specs, etc?

I've done this to 2 of my G-sedans one was a 07 5spd auto with tech package and the other 08 6mt sport . And after cleaning my tb on both cars. I've encountered problems with my idle like high idle at 1800 or fluctuating from 1200-2000 rpm like your car has no idea where to idle. I think if u open the butterfly valve or move it more than it needs to be opened then most likely your gonna have to do that pain staking idle relearn, throttle position relearn,and idle air relearn etc. It's such a hassle, but you'll get it eventually. Some may get lucky after cleaning there tb and won't have to do it at all or some just suffer lol. Or another method I've heard of is if u disconnect the battery for more than 5mins then it should work back to normal, but most of the times it doesn't. On my 07 5at sedan. It had a high idle at 1800 after cleaning my tb. I did the whole idle relearn process along with the whole 9yards it took me 7x to finally get it and it fixed my high idle. On my 6mt sport I had the surging idle that went from 1200 to 2000. It was embarrassing cause your car sounded like it was retarded, but someone at the dealer told me it should fix itself once the computer figures out everything is out of whack since technology now a days are so complex and high tech. I just waited it out it took my car almost a month of normal use and driving for it to relearn where it needs to be idling at based on my driving habits. And I guess that's the lazy way of doing if u don't mind embarrassing yourself when ever rolling up to a red light with cars on either side hahah.

Thank you 🙏🏾

Wtf! Your engine cover actually has the logo emblem on it!

Thank you very much

Nice! I believe the torque specs are 8ft/lbs cris cross pattern.

Nice video but because electronic TB I think it's wise to remove the negative battery cable first before anything

Hey great video very detailed. i was wonder if you could do a video on how to adjust the headlights.

Good job

Is it necessary/better to disconnect the battery doing this?

I agree..."do not take off any of harness of electrical connectors from the throttle body...otherwise you need to do throttle relearn..."...but, I think that one is easy...it is just "make sure pedal is fully released....turn it ON but not turning on the car...then turning it OFF for 10 seconds...' it would be the IDLE relearn procedure more difficult to do if the throttle body is replaced...please refer to mechanics manual....

I did not have any problems after this I cleaned mine. If you take any of the wires off you may have to do a relearn on them. I'd recommend cleaning them every 30,000 miles or so.

Is is necessary to do the 3 step re learn if i just clean the throttle bodies?

When do you have to replace the rubber gasket for Throttle body?

What I don't understand is...when disconnecting the battery...why is that not the same as disconnecting the "harness of the electric throttle control actuator (throttle body)"...and needing to relearn the system...apparently not...but, why is it not the same thing...I am confused...

Thanks for this man. I appreciate it. When you cleaned them, did you touch the butterfly at all? Like push on it? I heard if you push the butterfly you'll have to do a relearn process.

I’m having issues with my g37 maintain the rpm when I turn it on, like it will turn on the turns back off, I bought it from a guy that had it out all the time and it was very dirty and dusty on the inside.could this solve my problem

need "Idle Air Volume Learning" or hell !!!

Good Job, How often should you do this??? Better idle?? Thanks, youtheman =)

If after you clean the throttle body and your having idle issue; you need to disconnect the battery for 5 minute for the computer to relearn. Reconnect battery idle will be back to normal

Yea, tons of people complaining about this process causing problems with idle after the cleaning. Many speculate that it is the movement of the throttle body butterfly valve. Perhaps it is user error? Not replacing MAF correctly or not tightening down throttle body bolts properly. Or perhaps the sensors which read the exact position of butterfly at shut down and after cleaning the slight variation causes problems and a need for reset. Batter disconnect or not disconnect is another variable...if its connected does this allow the sensors to still read the position of the butterfly and adjust acordingly while a complete battery disconnect does not...?? Unsure this video does not mention the disconnection of battery and he did not push on butterfly valve...either.

g37x 09. cutting throttle at 2500k rmp. any suggestions

Do you need a programming after cleaning? How many times can you be clean?

why do you need to clean it? it is only moving the butterfly for increased air flow during throttle operation...... does it stick when it is dirty?? dealer said i have an idle issue and need to replace them.... 3500 dollars they quoted. is that crazy or what! I call rip-off on that quote

Where is the bank 1 camshaft sensor on this very engine????? People say in back but it looks like its right up front do you know??? I can't find a diagram anywhere

Wanna clean my tb , but I’m scared I’m gonna get the bad 1-2 rpm after 😭 I just changed my atf it helped a lot with my poor idle . But still jumps a little

hey i have questions. after i clean. do i need to reprogram the system or not.

I wonder if we really have to disconnect the battery for cleaning the TB and or the MAF sensors.

Do you mostly work on mustangs or will you do any Infiniti G37 videos

I have an 08 g35 sedan i swapped it for a 350z hr engine same engine just less miles and it turns on but doesnt let me gas it it only runs when i have it on drive by itself the normal slow speed if i press the gas it doesnt go. I called a electrical mechanic he told me one throttle body has more voltage then the other also the slip and vdc light stay on. Does this have to do anything with it ? Or is it the throttle position sensor? Any help would be appreciated thank you.

Is this the same for a FX35

What issues might arise from a dirty throttle body?

Hi hrkhaliki, Thank you for your video, I used it step by step to clean my TB+changing the Spark pugs as well. But after I cleaned the TB without disconnecting any electric harness (with opening/closing the butterfly+Disconnecting the (-) battery terminal) the RPM was unstable going up/down (2000 to 1000) in idle mood, the ECE light came up tried ECE erase, relearn procedures many times but both didn't work out. I drove in the car over 70 Miles after cleaning the TB and still getting same problem, would you please help if you have any Tip or advice you would share. thanks and will be waiting your response

Should I buy one or clean it first

Any improvements to the MPG?

I did this and mad codes popped up 😔 all 4 of these P2133 | P0228 | P1233 | P1238

You dont need to take them off to clean them...

Thanks for the video. I did mine and now the car is idling around 2200rpm. Anyone encounter that problem?

he's an Idea have someone in the car with key on engine off and have them floor the gas, this should put you're Nissan in flood model opening the throttle just enough to clean them well, make sure you have you MAF connected as that will throw a code....you're all welcome.....Subie fanboy.... over and out...

$700 is what they wanted at 2 diff garages to do basically this to change my spark plugs, not even cleaning the throttle body, but to remove the hose and throttle body so can change the plugs. WTF MAN. Honest to goodness, this is not $700 worth of labor. Reason #1 I hate taking a vehicle to a garage. Honestly I'd prob paid 2er 300 to have them do it but h*ll no. Can't trust no one concerning $ these days. This is why our economy is in the state its in, jus my opinion.

how do you clean maf

Dump the Blow-By to the atmosphere. Install new TB gaskets if ur over 30k miles or 4 years old....(16175-JK21A)K&N crank case part #: 62-1340 or Vibrant Performance part #: 2166. TorQ on those allen bolts is 75 INCH/LBs

Do not.....i repeat.... DO NOT MOVE THE AIR FLAP ON UR THROTTLE BODY. U will have to do a relearn afterwards.

Don't be a beeoch. Just open the valves, but make sure you don't disconnect your battery. Just do an ecu reset (without pulling the negative) and do a relearn for idle air.

I want to no how reliable this engine is g37?

Good job
