yes, but no. good news, bad news. i changed a couple injectors today. it cleaned up the stft and suspected lean condition. however, it did not solve the popping at high rpm issue. i swapped the plugs & wires after i realized it still has issues. didn't test that out yet because of rain. most likely going to smoke test the car tomorrow in search of vacuum leaks. fwiw all of my original injectors looked perfectly fine, 0 build up or any damage otherwise. i was also going to snap a pic of the ball end of a USED fuel line to show exactly what happens when you tighten the lines up and why it is difficult to reuse them, but i forgot. ill get one tomorrow.

heres a pic slightly encompassing the colossal waste of time i endured today. i was very surprised at the lack of torque applied to the fuel line connections.

edit: also surprised at GMs use of velcro to secure the injector harness to the rails.
