clean body

recently my mech cleaned my throttle body. he removed the air filter and spray while revving. then he used a liquid while still revving. within 30 minutes he was done. but im not sure if its the best way. i asked mech y he did not open the throttle body and clean it he said better to do this way cause it cleans the sensors too. im not sure if he is right though.

You guys talk about Throttle Body cleaning huh......lucky you all running Single Throttle Body woo. Like we play Toyota Four Throttle lagi pening kepala hahahaha. Other people use one we have extra 3 to think about hahahahaha.

But anyway, this is how I would do Throttle Body cleaning:

It was like almost 1mm of dirt hahahahaha....


Doesn't look too good here either.....



After some spraying, scrubbing and TWO cans of Carb Cleaner and a healthy support of Lacquer Thinner.....

Notice the brown dirt splattered all over the engine block wall and outside? well that's HALF of the contents sprayed out from the intake passages hahahaha



Oh the ISCV valve also gets the same treatment, no pics here but I think our fren can post it up for us.

Important Note:
The example shown above clearly state the importance of using Oil Catch Tank becoz I am absolutely sure that all the dirt and oily grime comes from Engine Oil vapour sucked into the PCV pipe and Cam Cover Breather port. Fuel varnish and carbon alone will not be as dirty looking as this.

Roger and Out!

Members,

Read my post and experience in the Mazda/Ford section on Throttle Body cleaning. I explained it in detail and read other posts by others. See my disclaimer also.

The one I'm using is Zip Decarbonizer. 2 bottle system ; one spray and the other liquid. Cost of cleaning = Rm85. Cost of fuel saving = heaps!!

Only remove air filter and use the spray can to spray into AFM. This will go thru the TB and the intake manifold and the valves. The liquid will require a tube connected to one of the many hoses at the intake manifold. The liquid bottle will look like the car is having a drip as when you're really sick lying in hospital bed with a drip bag. Kekeke.

Anyway check out my post as a lot has been said there.

WARNING!!
If you use carb cleaner on your throttle body, you can kiss goodbye to your TB cuz it says Carburator Cleaner. Not for injection cars with TB. Those who have used carb cleaner on your TB, be prepared to replace the whole TB as it's gonna kong one of these days.

some of you said that your car jerk before the cleaning...
can define the jerk here?

like when your car is idle, not moving, rpm low and the car engine vibrate a lot?
or in the middle of driving, you can feel something "pull" the engine even your right foot still on the pedal?

and how many zthian here have EFI engine and send for throttle cleaning?
will there be any difference cleaning throttle body for EFI and Carburetor?

I was told by 1 of the mech at Cheras that my EFI need a "machine" to do the throttle body cleaning, not just spray. And I think the charges is more than 100 bucks. Can anyone verified that?
