Thank you rkvons - I had assumed AC Delco was original but kept seeing Delphi appear on some sites saying it was OEM.

I did a brief check yesterday and resistance across coil pack was similar to others, about 6500 ohms. I checked the resistance at the injector harness and readings were about 14.5 ohms, same between A/C A/F & A/H. Today I will start removing the octopus of wires and remove the upper plenum. When doing voltage and ohm readings on the injector connection and injectors, what should values be? Also, I figured if I have to tear it apart again, it might be worth removing all injectors and sending them out for a Flow Test/Cleaning? Is this actually beneficial or is it a gimmick?

Thanks for the tips so far
