Aim: To clean injectors to solve the possible issues: engine hesitating, engine not revving smoothly
Required: socket set, rags
Steps:

Step 1:

Release the pressure of the fuel system by slowly opening the fuel filter banjo nut (12mm). Loosen nut one complete turn. Ensure you place a rag around the filter as fuel will slowly leak. One pressure has been relieved, tighten up fitting.

Step 2:
Disconnect the connectors on the injectors

You can now remove the fuel rail from the injectors. Do it one injector at a time. Fuel will leak at the injector inlet.

Now remove the injectors from the intake manifold.

Go to your local mechanic/auto store that can clean your injectors.
I went to Mekong in Canley Vale. They flowed it, cleaned and then reflow. They installed new filter and orings. $72 all up.

Install

Coat o-rings with engine oil (very light) and insert the injectors into the fuel rail.

Install the fuel rail with injectors into the intake manifold.

Align the centreline of the connector with the mark on the fuel rail.

Reverse the Removal Procedure.

Before starting the car, prime the fuel rail a few times.

Almost perfect.

Important to mention that you should release fuel pressure by removing your fuel cap.

Then onto your step 1.

+rep with hesitation.

because you didn't mention step 0^^

So this is how to remove the injectors for cleaning. Not how to clean them.

[Bludger]

common tiks, he's trying.....

[tiksie]

Didn't say anything wrong with it. I'll be repping him. :)

you need one of those sonic cleaners to clean them properly anyway.
Most mechanics don't even have the tools to do that, they just outsource them.
btw... Mekong spares is prob the cheapest to do it anyway.

Highly doubt that price includes removal of injectors. If it does, then that's damn cheap.

not including removal,,, removal takes 5-10 minutes,, and its easy for new comers and noobs to learn anyways give it a go ,,
