How to CLEAN a Throttle Body Nissan 350Z & Infiniti G35 (Nissan 3.5L V6) | AnthonyJ350

[@Big_Old_Dog]

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.

[@AnthonyJ350]

Thanks! Glad you liked that tip.

[@BillSW]

how long do u keep pressing horn to discharge? what about leaving bat disconnected overnight

[@Ootgreet1]

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.

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 ,

[@stealthg35infiniti94]

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.

[@AnthonyJ350]

Thanks for sharing, I have that stuff too, I believe a little residue after to help protect correct?

[@stealthg35infiniti94]

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.

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.

what if someone tuned your ecu , would the ecu reset sequence reset it back to factory tune?

I don't think so. I would call the shop that tuned your car to verify though.

[@MrSnakedoctor85]

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.

[@AnthonyJ350]

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.

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.

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!

[@AnthonyJ350]

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.
