oh, I didn't understand because I thought the oil was completely internal in the injector, I didn't realize that the o-rings were sealing oil inside the injector as well. I just assumed the injector body kept the oil internal, and the o-rings sealed the injector into the head.
So the nozzle of the injector fires directly into the cylinder, correct? Not into a plenum or valve?

I get a little stutter. I put in a TE modded HPOP which got rid of it but it came back a little bit ago. My injectors are still "new" from Rosewood so I don't think it's the o-rings. I feel like a lot of these problems with the OBS's are related to fuel which I plan on upgrading soon. Goin electric, gonna piece my own kit together, but I think that'll probably take care of that issue

And when it's rolling down the highway, it all seems fine. With my SCT plugged in for my "gauge" I can get to 15psi boost, so I wouldn't think I have any problems there, but who knows for sure....I will work through all the leaks or whatever is making my mess in the valley first, and do a buzz/cct check.
I seem to be able to create the stutter most often if I let out the clutch in first, let it creep along at an idle, when I push the clutch in, it stutters for a second or 2, still about 500rpm, just feels rough, and then just rights itself. When it's idling along under load, no stutter.
And since I cleared the 236 code, it has not returned.
Is there any diagnostic way of checking injector o-rings without taking them out?

I'm afraid the only way to check is to pull them. It's a lot of labor but pretty straight forward. I hated pulling mine because prying them out proved to be difficult, I actually cracked one of the solenoids mounted on top of the injector... Very frustrating
