Hello it's Alimek in today's video I'm gonna show you how to clean throttle body without removing
and also I will be cleaning fuel injectors without removing as well but I will take them out so you
guys can see in real time how the fuel injectors look like when they are clogged and how the fuel
injector cleaner effects on them. So few days ago I was driving my car on a road and suddenly
vehicle stability control and check engine light came on after I felt misfire and shaking engine
So after I got back home I had to use my OBD scanner to know what causes that problem
because when vehicle stability control comes on with the check engine light
it means there is some serious problem that makes the engine reduce power
So after connecting CG solid OBD scanner it will power up the scanner
now we can put the key on ignition position
Next we gonna press the OBD icon it gonna take some time to scan
and the red light comes on when you have a problem with the engine
It already tells us that we have one error code let's find out what it is
The code is PO303 cylinder number 3 misfire I'm expecting to have clogged fuel injector
because I have replaced spark plug before not long ago
and the car not that old to have failed ignition coil
So I will be using O2L cleaning kit you can use this kit for cleaning fuel injectors,
throttle body, intake valves and many more and I will show you how to do the same procedure
without using this kit as well because using this kit needs compressed air
so not everybody has a compressor at home
Here you can fill the canister with cleaner
whether if it's fuel injector cleaner or intake cleaner
compressed air connected here and you can adjust the pressure with this knob
If you have a garage and working on your car just like me
definitely worth to buying this kit
So the first thing I will do I'm gonna attach this nozzle to the canister hose
and it will replace it after mass airflow sensor
but not inside the fuel injectors
Let's hang the canister under the hood
So for the cleaner I will be using seafoam it's safe for throttle body and the fuel injectors
Never use harsh cleaner for throttle body like carb cleaner or a choke cleaner
otherwise you will damage it and you have to replace it or reprogram it sometimes
So I'm gonna be using half of the seafoam for cleaning intake and throttle body
and the other half I will save it for cleaning fuel injectors
As I mentioned before I will be attaching this nozzle
so it sprays cleaner constantly to clean throttle body and the intake valves as well
Alright connecting the sharp air
I regulate the pressure on 30 psi
You can go up to 60 psi as well but I wanna have more cleaning time
If you open the lower valve
This is how the spraying pattern looks like with the 30 psi
It will take about 5 minutes to finish the seafoam
Next I'm gonna remove the filter box rubber boots
Insert the nozzle and put it back again
Make sure to tighten back the clamp
otherwise you will have vacuum leak and get more error codes
Alright let's start the engine
After running the engine for a while and reaching idling temperature
I'm gonna open the valve
So I'm gonna let the car idle till it finish all the cleaner
It will loosen up all the carbon buildup on the nozzle tips
So while the engine running on cleaner
I will explain how to do the same job without using this kit
You can get a seafoam like a spraying can
It comes with a long straw
Insert the straw after mass air flow sensor and spray with the engine running
But with this kit you have more consistent spraying pattern
And you don't have to keep your finger for 5 minutes till it finish all the can
Okay after finishing all the seafoam
I'm gonna close the lower valve
Turn off the engine
And remove the nozzle
And here is how the throttle body looks like compared to how it was before
Okay next I'm gonna use this adapter for cleaning fuel injectors
There wasn't much room for showing you guys a good angle
So that's why I had to remove filter box
So it will be obvious where I connected on the fuel rail
So what I did here
Removed the fuel line and connected cleaner adapter
We gonna run the engine with the cleaner instead of fuel
And then put the filter box back on the engine
Next I'm gonna remove the shop air
Depressurize the canister
And then filled again with seafoam for cleaning fuel injectors
I just pour the other half of the seafoam and connect the shop air again
The important part of this procedure
We have to disconnect the fuel pump so it doesn't pump fuel back on the engine
Because we already removed the fuel line
I'm not willing to run the engine with the fuel
So I'm gonna disconnect the wire harness before doing this job
For most cars you can remove the fuel pump fuse
But on Toyota Camry
Fuel pump fuse responsible on fuel injector power as well
So the engine not gonna run even we are feeding fuel with the canister
All right fuel pump fuse back on the engine
Now I'm gonna open the lower valve and start the engine
We gonna let the engine run with the cleaner till it finished all the cleaner
And when the canister about to get empty
The engine will start to shake and that's the time to turn off the engine
So here is the engine running with the check engine light still on
And the fuel pump harness disconnected
So how we know the cleaner working and cleans the injectors
So I took the injectors out of the engine to see the moment when it cleans the injector
So this is just for experiment reason to show you how it will clean it when it's on the engine
So I'm gonna start the engine to power off the injectors
The car obviously not gonna run
But you will be able to see how the faulty injector working
And how it gets better after the cleaner comes out and dissolve the carbon
So I'm gonna let the engine run with the cleaner till it finished all the seafoam
You can do the same procedure without even using this kit
You can make a DIY adapter and connect the adapter on a car up cleaner and run the engine with it
I have a detailed video about that
I will put the video in description box below and YouTube card if you wanna check it out
The last thing I'm gonna do I'm gonna zero out one of the chips and drive the car
Let's see after how many kilometers
It will turn off the engine light without using OBD scanner and erase the code
Alright it's been after 56 kilometers
Engine light and vehicle stability control turned off without using OBD scanner and erasing the code
If you really fix the problem check engine light will turn off after driving for a while
Keep in mind you don't have to remove the fuel injectors
I just show you how it was before and how it cleaned it
Alright that's it for this video
