So I have some hope I may have found the issue. I monitored the TP1 and TP2 voltage through the PCM to make sure it was a smooth ramp. Just sitting in the car with KOEO I could go though the sweep and listen to the throttle body open and close. I then had my wife start messing with the wires at the TPS and motor to see if it changed. Well it did. Specifically just wiggling the wires right at the TPS connector. You could hear the throttle plates open sporadically even though the throttle pedal was not moving. Got a new connector on order from Rockauto and hopefully that fixes it.
Good job. Intermittent issues are such a PITA to locate.
