Cleaning Throttle Body!

[INTEGGRA]

Hello everyone.

About a year and a half after i purchased my DA9 i started to notice uneven idle in the RPM some times sitting above 2000rpm and other times it sitting at 900-1000 around where it should.After a few weeks after that it started to not only uneven idle but it jumped from 1000-2000 and reving up and down like i was sitting the gas.After asking 3 different places and machinics i got all different respones
1:It need to be taken in and computer adjusted.
2:It need a whole new part from honda costing over 200$
3:Nothing wrong with it apart from it being annoying and better off living with it then paying the expence.

After reading about this DIY project in the current issue of HOT4's i thought id give it ago.

A dirty Throttle body can cause all sorts of problems.
Uneven idle,slow response and lack of fuel efficiency and even making the car stall.

What you will need
Head to Super Cheap Auto
TFT Part Brush
Nulon Carby and Throttle Body Cleaner


Step 1. Remove the intake pipe.
On my DA9 its just one screw clamp and then a matter of unclipping the intake box.


Step 2:I removed the 3 pipe connected to the intake pipe. You dont have to do this but its alot easier to get in.

Step 3:Remove the Intake pipe right off as i did or if you dont want to follow step 2 you will have to work around it.


The Gold cap is the Throttle Body Blade.

Step 4: Spray the insides with the cleaner i sprayed for quite a while making sure all the black dirt came out.


Step 5:Scrub the inside using the brush.I found it helped to spray the cleaner on the brush at the same time.

Step 6:Open the Throttle body blades buy pulling on the Throttle with your hand.I also opened it then put the rear end of the brush into the blade to hold it open so i could spray right around.

Step 7: Try remove all the black dirt that is visible you would be surprised to see how much there is.

Step 8: Reattach the intake pipe and make sure you reattach the 3 pipes you removed aswell.Tighten it all off.

Step 9:I crapped myself when i went to turn the car on,They dont mention this part in the magazine.It doesnt start very well when you first go to start it give it abit of gas and it will start up.Mine sounded like a harley for about 5 seconds.

Step 10: Let the car idle it will blow abit of smoke at first and sound abit rough.Once the cleaner has been passed through it will idle smoother and you will notice the difference.I ran mine for about 5 mins.

Doing this i really noticed a improvement in the RPM very much so when over 3500rpm it feels alot more presise.

But the main thing was it stopped doing the stupid reving and is sitting on a even idle.I drove for about 30 mins after and it is still in the correct idle.
Very well worth the 15$ and the 30 mins i spent doing it.Took a while longer taking the photo's haha.

Just thought id share and if you got a spare 15$ bucks and half a hour of your time i suggest you do this! Very happy with it and well worth it.

Just if you stuff anything up dont blame me ok!

Did this to the TB on my car on the weekend, looked clean inside at first but after spraying the cleaner in quite a lot of build-up etc came out..

Made a big difference to my idle - a lot more consistent now and overall car just feels smoother, defintely recommend this diy!

I tried this as well. I drove it a bit right after I cleaned the TB and noticed it revved freer. The next day I disconnected that battery to install a stereo. Then I drove again...however it idles about a 50 rpm range up then down and up then down (in a range from about 1000rpm to 1050 rpm)...So does anyone know what has happened?

was quite bored today, so i thought i'd give this DIY a try....

mine looked quite clean, untill i sprayed the cleaner on it. gave it a good o scrub using a toothbrush.

fren was quite amazed how black/dirty the rag was when i wiped it down, so i did his too.

havn't noticed any difference. but hey, least my TB clean now

Did this around a few hours ago on my car.

I too was suprised with the amount of junk that had accumulated in the TB. I gave it a good old scrub with a tooth brush as well (no my own personal one :P) and it was looking pretty smhick.

Car was a bit of pig to start but gave it some revs and held it a 2thou rpm for a minute. Defo an improvement rev range!

A must for any new comers into DIY (like myself)

Good write up too.
