Actually he did not set the idle correctly all he did was show you how it looks inside the TPS. To correctly set the idle you need to disconnect the TPS harness and loosen the screws(2) holding the TPS. At full throttle the tps should be 4.~4.02 volts if it's not adjust the TPS back or forth till the target number is matched. After it's set screw the TPS down and reconnect the harness and start the car up. Once the Z is warmed up your rpms should be 800-850 rpm. If not disconnect the TPS harness and with a long Phillips screw driver adjust the AII valve. Clock wise to increase rpms and counter to lessen the rpms. Once the target rpm is hit then reconnect the TPS harness and you're finished.
If your idle is normal then do not touch the TPS.
