Code P2104 and stalling

Well my truck stalled a few more times since cleaning the TB. P2104 is the code it stored and my CIL is on constantly now. Actually it runs better with it on than it did before.
I've done a search and it appears that this is usally a Throtle Position Sensor. I'm pretty sure I have the latest reflash and the stalling started happening out of the blue with no problems before hand so I'm thinking it is a mechanical thing.
Has anyone had any luck just replacing the TPS and it correcting your stalling problems. Di I need to have it re-flashed? What does the TPS look like and where is it mounted, I now it's on the TB but so is the air idler, TB motor, etc...??? Also, does anyone know how much these cost and a good place to order from? Any guidance is much appreciated.

I just talked to a service advisor at Ford. He mentioned that he thought(but wasn't 100% sure) that there were 2 TP sensors, one on the pedel and one on the TB. Does anyone know if this is true? If so, which one should get replaced first?

1 TP on the throttle body 0-5v increasing signal

3 APP on the pedal two 0-5v increasing and one 5-0v decreasing signal.

Thanks! So since there is a sensor just for decreasing speed and it only stalls when letting off the gas to turn would it be a viable option that only that sensor could be causing my issues? Heck, I might have just kicked a wire loose or something although I couldn't get that lucky.

This DTC is an informational DTC and may be set in combination with a number of other DTCs which are causing the FMEM. Diagnose other DTCs first!!!!!!!!!!!

P2104 means something went wrong and the PCM defaulted to forced idle.

There is another code present that will give you more specifics on why the PCM went into forced idle.

I was running the same code....had been stalling randomly every few weeks for the past 6-8 months...finally thru a code the last time and did a little research. I pulled the codes myself and told Ford to clean the throttle body, change fuel filter and replace TPS sensor on throttle body. Also reflashed to newest PCM files (yes reset your programmer to stock before taking it in...will cause a new Hex code and may lockout your programmer if not reset to stock). Ended up being $439 with tax out the door. So far so good...been 2 weeks and running strong. If the TPS sensor does not fix issue you may need to replace throttle body or look at the PCM itself. Mine thru a code for the Throttle stuck closed as well.
