no coil packs - Only one coilIf you have no luck with coil packs. I know I’m stretching here but check as many grounds as you can find. Then check your click spring. I had a problem of cutting out for years. Had free extended warranty. They replaced everything. Anyway years later met a electrical engineer from Chevy. Said guys overlook it all the time.
I agree 100%, however my comprehension has gone way down since I turned 63. I have a degree in Electronics Engineering and I am just getting slow. It may even be in the drawings you uploaded, but can you tell me specifically which of the 3 connectors on the PCM has the o2 sensor wiring, and which pins on that connector represent which sensor? Both sensors have 4 wires each, 2 white, 1 gray, and 1 black. Thanks againi would ohms test wires sensor to sensor, then to another sensor then to ECM, in all while no mice have chewed wiring, i wouldn't open the vehicle harness, just perform resistance checks, as for 2 o2 sensors to fail with same failure, IMO they would share a signal , ex. ground. because there are 2 individual signals to ecm. i apologize if im confusing, in my head its clear lol. sent you a IM
forgot to mention, all sensors share the same ground supply from ecm(in previous picture)so one wire gets split at numerous points(inside the harness)
