the throttel,key reset thing????
 

ok how do you do the reset? like turn the key on hold down the throttle turn key off ect,ect.... can i get the run down on that?

Disconnect battery(s) for 30 minutes, then reconnect
Key to run, but do not start.
Depress the accelerator all the way to the floor and back up, taking 3 - 5 seconds each way.
Turn the ignition off, and your done. This is the APPS reset/relear procedure.

Yep what Ryan said.
APPS Reset Procedure
This procedure has shown to help 24 valve ISB engines. It is basically teaching the fly by wire accelerator on these trucks to reread the position of the pedal and it's limits. Most complaints this will help with is poor acceleration, improper shifting, bucking in 5 and 6 speeds. Has been known to increase fuel mileage in some instances.

1. Set parking brake
2. Disconnect negative battery cables on both batteries
3. Turn ignition key to run(to drain any remaining capacitors)
4. Let truck sit for 30 minutes( this is the recommended minimum)
5. Return ignition to OFF position
6. Reconnect both batteries and secure, not a timed event
7. Turn key to run position(not start) and depress accelerator pedal slowly all the way to the floor
8. Allow pedal to return to top position slowly
9. Turn ignition switch OFF
10.Release parking brake

is there any reason you would want to do this? I doubt this has ever been done to my truck and it has 104k

This resets the APPS Sensor (TPS) when you disconnect the batteries or replace the APPS sensor.
