I am in the process of replacing the intake manifold as it failed. I have all 8 injectors sitting on my bench. I was wondering what I should do with it. It has 175,009 miles and this is the first time it is out of the truck. Can it be serviced or should it be replaced? Or just reinstall it and wait until it fails. Thanks

 

Injectors aren't that hard to change, I'd wait until they fail before replacing them, assuming they ever do fail on you.
