throttle body motor for V6 why not v8

[silver03cobra]

So I see dorman has a 911-102 for the v6 why not they have one for the v8??? I have the etc fail safe going on... Just put all new COP'S and still nothing..... I am getting the following codes:
P0122
(TP Sensor Circuit Low Input)

P0222
(Throttle Position Sensor B Circuit Input Low)

P2104
Throttle Actuator Control System - Forced Idle. Throttle actuator control system is in FMEM mode of forced idle. PCM damaged
Multiple ETC system faults
Bad APP sensor


P2111
Throttle Actuator Control System - Stuck Open. PCM fault status indicates throttle plate is at a greater angle than commanded.

Any help would be great... car starts but has rough idle throttle peddle does nothing. Thinking I will go buy a TPS.
