Question about Ford E-150
You should not have to remove the entire Throttle Body, the TPS should be at one end or the other of the Butterfly Valve that is controlled by the Throttle Cable. It should be held in place by 2 small bolts or screws.

Try cleaning the IAC (Idle Air Control valve.) by buying spray carb cleaner and removing the air cduct from the engine. On the fuel system side look into the hole and try to locate 2 holes on the side . With the engine running at about 1200 rpms, spray about 10 seconds worth of cleaner at the 2 holes. Turn the engine off. Let the cleaner soak. Then repeat procedure. The IAC can also be removed and cleaned if you wish.

I think the terms "Throttle Positon Sensor", TPS and "Throttle Body" can be misleading at least in regards to the 04 Camry.
My 04 Camry gave a diagnostic reading of P2121 for my problem "Throttle PEDAL position switch D circuit". However, we changed out the complete Throttle Body/TPS (Toyota Part #22030-0H020) that did NOT fix problem.
The 04 Camry TPS Electronic Module "Throttle Positon Sensor" is factory assembled and riveted to the side of the throttle body. The only way to service/inspect it would be to cut off or drill out the rivets. Not sure you could open the darn thing if you got it off, but that seems to be the only way Toyota sells them!!
Hopefully a new Throttle PEDAL Position Sensor (Toyota Part # 78010-33010 PEDAL ASSY, ACC)
will fix it. This is located under the dash near the accelerator pedal.
So, now I would recommend FIRST to replace the "Throttle PEDAL Positon Sensor" (it is much, much cheaper) and then the Throttle Body/TPS assembly!! Unless of course, you get a diagnostic code as you did for "faulty throttle body!!

Not 100% sure on your exact car but nissan TPS usually are on the opposite side of the TB from the butterfly return spring.

Testimonial: "thanks a million no information on installing & adjusting in repair manuel"
you have a fuel pump relay that may be defective, or fuel pump or maybe the crank position sensor,a cam position sensor.the best thing is to have a scan performed with an obd1 scanner and you will know where to start the repair.
