There's no way for any of us to diagnose your car from behind a keyboard. But have you pulled any codes from your Z's diagnostic system?

P2122 means the low voltage is detected with the TPS (throttle position sensor). P2138 is related to the ECM not being able to read the signal from the electronic throttle itself. I've never been involved in swapping a manual tranny into a automatic-equipped Z, but IMHO you need an experienced Nissan tech to help you figure this out BEFORE you start throwing parts at it. .
