APPS issue need help!

Ok so my 01 X has been having a stumble at light throttle and it got worse where it would dead pedal 3 or 4 times a trip so I bought a whole assembly off auto warehouse on internet. It came looking nothing like the pedal assembly I have after getting it off so I determined that mine has the removable apps. So I ordered that at the local Carquest and got it this AM. I drove the X to my shop and took the old apps off and put the new one on. Start it up it surged one time then nothing but idle. put the old one back on nothing but idle. un hooked batterys to clear codes and reset PCM, Got a can of contact cleaner and sprayed the heck out of the idle validation switch and re installed nothing but idle tried the old one again nothing but idle. Is there a way to reset the apps or re calibrate it? what am i missing here?

I think your Dodgeness is showing

In Ford terms I'm guessing your talking 'bout the TPS - right?

I have this for the reset procedure (sounds like you've already tried that though) "Unhook your negative battery cables, for about 20 minutes turn your key to the run position to help drain off all capacitors, then turn the key switch off. Reconnect your negative cables and turn your key to the run position, but do not start the truck. Slowly depress the throttle pedal, to the floor, then slowly return it to the idle position. Shut the key off."

Are the gauges also not working? It's not uncommon for the shorted OD wire to blow Fuse #45 and cause a problem with the TPS. Maybe, if yours isn't shorted enough to blow that fuse it's confusing things by drawing the voltage down...

Have you ever looked at your OD wires? If not, that's where I'd start!

Im at a loss, I double checked the part number to make sure I had the right one. ITS EVEN MADE in USA. I thought I read somewhere that if the computer (PCM) is actually completely reset that it will cause the gauges to cycle all the way back and forth the first time you turn the key to run. perhaps overnight with cables off is required or a dealer visit.
