TPI problems

Finally fixed my car for like a month and then back to having more problems with it. Have replaced so many parts on it. Car is an 85 305 tpi. All new tpi gaskets, new South bay 19 lb injectors, fuel pressure regulator diaphragm, IAC valve, egr valve and egr temperature sender. Also put a heated three wire ac delco 02 sensor on it. I uploaded the pictures of tuner pro data logging it. It seems that the o2 sensor isn't getting any voltage. Also the volt gauge on the gauge cluster hops around too. If you see anything else that is out of wack in the picture, leave it down there. Thanks

Re: TPI problems

You might check the continuity on d7 of the ecm to the o2 .
