Throttle Fault comes on dash after initial start up of cold engine.

What led you to the throttle body? The best place to start is by having the dealer read the stored diagnostic fault codes. They will get you to the circuit that needs diagnosis. There's a position sensor on the throttle body, another one on the gas pedal, and they both feed a computer. That's an awful lot of insane nonsense to replace a simple, reliable throttle cable.

I ran a diagnostic myself and got no stored fault codes. Maybe I'm insane but I thought this model car was a drive by wire and did not have a throttle cable. I've been an Industrial Mechanic for over 30 years and am having trouble accepting the fact that I cannot repair my vehicles myself.
