Step 1



After removing everything you can move the air box out of the way, I just placed it on top of my battery so I didn't have to disconnect my MAF.

On to the next step: Step 2



Now slide the coupling off the TB and you can now move this out of the way as well.

Step 3



To remove the throttle linkage just open up the butterfly to make slack on the lines and slide the base section out of their little slot in the linkage setup.

Step 4



Now you can slide the TB forward and remove the plastic gasket/air guide.

Step 5



After this you can completely remove your TB for cleaning.

 

TB removed



Intake inlet dirty



TB dirty front side



TB dirty backside

If you want to soak your TB in gas or some type of cleaner you should also remove all of the electronic parts at this point (there is only two pieces to remove if you want to do this).

I didn't have time to do that so I cleaned everything with a toothbrush a brilo pad some engine degreaser and Sea Foam Deep Creep.

 

Everything cleaned up:








Installation is just reverse of removal.


This did not cause any SES for me, but please do this at your own discretion. I am not responsible for anything that you do to your car, please becareful and be sure to reconnect everything you disconnect, especially the two rubber lines which are fuel lines.

 

looks like the writeup i did 3 years ago using these pics

Huh... I did it because I could never find one and I guess most other people couldn't either because last time I posted about cleaning my TB everyone wanted me to do a write up. Oh well, how'd I do on mine?

 

nice write up,...

 

Thanks for the write up, that's great, how long did it take you to get the TB off? Notice any difference after the cleaning?

 

Yeah i would like to know that too.

 

I would be aware of using any (not dedicated) solvents to cleaning TB by the risk of damaging the protective coating inside. There are many dedicated TB cleaners. Also, actually it’s not necessary to remove the TB. Just open the butterfly and with a toothbrush you have access all the way down to the intake manifold. (Don’t do this on VQ35!!)

 

good advice in red,.. sooner warned us all of this a week or so ago. . .

 

Nice write up.

 

nice write up

 

wow did you ever change your air filter?
Have you cleaned IACV valve body while TB was OFF?

 

Way to go... lol, if you're dedicated enough to clean the throttle body, I'm sure you could find some dedicated TB cleaner!

Fantastic write-up though.

 

It only took me about a half hour, making sure to take pictures along the way including cleaning time. Reassembly only took me about 5-7 minutes. Right away I noticed the car started up quicker and seemed to idle a little smoother. So far the only other thing that I have noticed is that there seems to be a little better throttle response.

 

nice write up.

 

I have also noticed a slight increase in gas mileage.

 

can anyone give me quick reply on how to remote throttle body linkage in step 3?
