LS Injectors - easy to do?

[Jader1973]

My Commodore has a rough idle and I suspect it’s the injectors (or an injector).

I’ve had a look at the workshop manual, and YouTube and relaxing them looks pretty easy, provided you don’t cause a leak. Is it?

I’d rather avoid paying a small fortune to get someone to do it if it is a simple DIY job.

It will be physically impossible to change injectors and not cause a leak of some sort.

Injectors would be an unusual diagnosis though, unless there has been something to cause them harm.

This kinda shows some assembly. It is not a difficult job by any means, however, if you screw something up and leak fuel all over the place, the consequences can be severe.

But don't you just replace the O-ring when an injector has been out?

Unless you have an actual reason to change them, no.

Yes , it is an easy job, you can do at home. First crank the engine with the fuel pump relay out to lose fuel pressure, then just swap out tge injector
