Pull out all the injectors from the fuel run

Do visual inspection for all injectors, this injector that all the holes are open not clogged and it have some burning oil from PCV system

Remove the O-rings. It’s a good idea to replace them whit a new one, but sometimes if they are not compressed sideways or cracked, keep them.

Remove filter strainer with a wood screw and pull it out. Once a filter be pulled out like this, it will be damaged and we have to replace it with a new one.

DIY adapter: a hose that fits on the fuel injector glued to a car cleaner straw and use hose clamp to prevent it from popping out

Here we use counter cleaner as a solvent

Use wire with elevator clip 12 volt battery since fuel injectors need power to open and close the solenoid.

You can use your cars battery as well. Sometimes we used to use 9 volt batteries , you should be able to hear the clicking sound of the solenoid. We made a wire whit a push switch for better operation it.

Connect the straw on a car cleaner can and push the car cleaner nozzle and give it powe at the same time.

Clean the burned oil as well and wipe raw
