steady 2k idle no no throttle action

I have a mazda 3 5 door with a 2.5l
The car all of a sudden pegged a 2k idle with no action when I step in the gas. I can drive the car but only to a speed of the 2k idle...there is no response when I step on the gas.

p0123 throttle positioning sensor/switch
p0223 throttle pedal positioner switch

I had the car in a shop and they replaced the whole foot pedal assembly
I brought the car home and replaced the complete throttle body with throttle positioning sensor
Both OEM parts.

i started the car and it was at 2k.
I then shut off the car disconnected the battery waited a few minutes.
I started it and it was a perfect idle with full action on the gas pedal. I thought it was fixed.
I placed it in drive and it went right back to a 2k idle with no pedal and the codes appeared again.
guy next store tried to clear the codes but they came back on in a few seconds.
we reran the codes and the same 2 appeared...

BUT i just replaced them....what the heck is going on....dont know where to go or what to check....PLEASE HELP!!!!

Wondering if the floor-mounted accelerator pedal design contributes to these issues. Also, don't all Mazda's use this same type gas pedal?
