12-15 hours mainly because you'll want to let the injectors soak in solvent overnight.

I used this DIY for my injector replacement with rebuilt units last year. Watch out because some of the instructions here do not apply to different years. My injectors came unlocked differently than this DIY states.
I'd guess at a time for this at 3-4 hours if you are swapping injectors.
Use O-ring lube when putting things back together.

Pulling Fuel Injectors............

I've taken out my air intake to replace my starter and wanted to change the o-rings on my fuel injectors and possibly clean them.

I'm having trouble getting the injectors out. I already removed the air intake as an assembly with the fuel rail. Can you give me any tips on removing the injectors.

Also, how should I clean the injectors, or should I not clean them.

Thank you for any help you might be able to give.

Cheers,
William

Are you referring to intake manifold or air intake? Because you do not have to remove either to get at the injectors. I'm confused.

I bought reman injectors because if you're going to all this trouble, get the critical internal parts replaced by the pros. You'll not accomplish much by soaking them yourself if you have had problems with them.

Why disturb your O-rings if nothing was wrong there?

I'm referring to the air intake manifold. The reason I started the project was to get to, and test my starter from the top instead of the bottom. Because I had to remove the throttle body, DISA Valve, ICV, and CVV, along with the air intake manifold I figured I'd clean up my fuel system and over haul my emission system. I'm replacing vacuum lines and such and thought to cover any possible air leaks by replacing all my gaskets (throttle Body gasket, Air Intake Manifold, and DISA Valve gasket) as well as any rubber like the o-rings on the injectors. My injectors seem to be fine. Just doing preventive maintenance.

However, my injectors are really in there. Just wanted a bit more information before I damage my injectors trying to take them out and/or ruin my fuel rail.

Any help is greatly appreciated.

Cheers,
William

There are clips in the injectors holding them in differently than the DIY, on my car. Once loose, they came out of my car easily.
