Idle/random issues also

[Prerunner06]

Small update.

Tested the TPS it did lose voltage in the same spot at 3/4 throttle. Got a new one and jeep ran better at the initial start up then something started to calibrate and my idle started to adjust settled down to 600-700 rpm took for a test drive was driving fine. Got home idle back at 1k put it in park 1500k. I blipped the throttle idle settles down to 6-700.

Also at the tail pipe the idle sounds odd almost like a miss fire but not as harsh don't know if it's the new header or just part of the problem.

I am still looking for ideas is it possible my throttle body is hanging up?
