03 V6 Mustang Convertible
My girlfriends mustang is having a problem:

Manufactor Controlled Vehicle Speed, Idle Control and Auxiliary Inputs
TPS/Pedal Position Sensor A Circuit High Input

When you start it, it stars a little then dies, you start it again but give it a little gas and hold it, it will stay on but run sluggish. You let go of the gas it dies.

Please Help Thanks John G

 

Sounds like your TPS (throttle position sensor) is bad , should read about 1v or less at idle I believe. I would replace that since it is used for idle speed (infact used all through the rev range of the engine).
You can also try unplugging the IAC (Idle air control) & see if that improves the idle, if it does then the unit is defective.
