Egr delete turned deadly.

I did an EGR delete on my 2.7 1998 SR5 which included plugging all the vacuum lines, putting the plates on the intake and exhaust. Tried both the ¼ watt 10k and the 5.6ohm resister and kept the EGR temp sensor in place . Reset the ECU. Started the truck up and it started fine until I started to accelerate and it started to bog down, backfired, and felt a huge loss of power.
I put the EGR system back to stock and it still has the same symptoms. It runs especially rough at 2k rpms.(Manual Transmission)

I also had to rewire the precat o2 sensor. But I drove it for two weeks and it was fine, but if anyone could give me advice on the pin configuration for that pigtail that would be awesome because I didn't find much online that matched my trucks wire colors. Or how to differentiate the ground wires

Thank you so much!! l
