Well, finally got my z back after changing the engine. All the hunting and stalling it was doing when hot has now stopped. Took it to Nissan went on the consult which showed nothing except that the new engine is from an auto. Which was good becouse it was nothing electrical. So it turned out to be that one of the dump valves would not close so vacuum was lost which caused the above problems. So no temp sensor or throttle bodies. Just a damn dump valve.
