Thanks, that’s a lot of great info. So here is what I did yesterday. I unplugged the computer and did a continuity test on all three wires, from the TPS pigtail to each of the corresponding PCM connector pins. All three wires showed good continuity so I would assume I have not breaks/shorts in any of the three wires. I called the guy that re-worked my harness and tuned the PCM originally and he seems to think that I might have damaged something inside the PCM which is causing a short. I did pull my PCM and give it to a friend to test on his new LS swap before his computer got tuned. When I got it back and went for the first drive is when I started having this issue.
