[QUOTE="Tiha, post: 1564218, member: 33189"] Hasn't changed. Runs 62-63 psi. I swapped o-rings on the return harness on those injectors. If they were leaking they are not now. Still questioning 1 injector. But no time to screw with it right now. Thinking back, when I pulled injectors to have them tested I never marked them. I figured the IAQ number would tell me where to go if I put them back in. The guy that tested them did not mark them either. Nor did he reference the IAQ numbers. Would have been interesting to see his test stand results compared to the fuel trim data I had. But I have no way of knowing now. The one injector I question. is -2.2 mg. None of my original injectors were ever that far off. 4 of them were questionable on fuel trims of half that amount. Hasn't thrown a code for the injector yet. No idea at what point it does or what the triggers are. That injector is in hole #4 which originally was looking really good on fuel trims, so that kind of rules out a mechanical issue in my mind.
