Throttle position sensor adjustment (NEED HELP)
I am having trouble adjusting the new TPS on my 22re. I printed something about it off the net but its really confusing. Anyone have any step by step intructions to do this. The truck is falling on its face spitting and spuddering aroung half throttle.

See below:

And at the end of that section is a simplified 10 step procedure:

And at the end of that section is a simplified 10 step procedure:
Throttle Position Sensor IDL-E2 Adjustment Procedure (courtesy of Frankenyota):
1. Loosen both screws attaching TPS to throttle body.
2. Attach multi-meter to TPS terminals IDL and E2 (the bottom two terminals on the TPS). You can use alligator clips to make this easier or use small ¼” lengths of vacuum hose to hold them on
3. Insert 0.85mm (22RE) or 0.77mm (3VZE) feeler gauge between throttle stop screw and throttle plate (see picture)
4. Move TPS body CW/CCW until ohms reading on multimeter is infinite (open)
5. Move the TPS body very slowly CCW until you find the end of the resistive strip, the meter will indicate <2.3Kohms of resistance
6. Move the TPS body extremely slowly in the CW direction until the meter goes to open/infinite again
7. Tighten the top TPS screw being very careful not to disturb the adjustment
8. Remove the feeler gauge and insert a 0.57mm (22RE) or 0.50mm (3VZE) feeler gauge
9. The meter should (hopefully) indicate between 0 and 2.3Kohms of resistance, if it does tighten the bottom screw and reconnect the electrical connector, if not go back to step 4 and try again
10. To check whether the adjustment was successful start the engine and insert the timing test jumper, if the idle speed decreases audibly it is working normally.
