It has no power starting out from a stop. on 1998 Kia Sportage

When you stop at a stop sign it just about quotes. Then when you go to start out it has no power. Sometimes it will stall and you have to put the gas pedal to the floor to get it to start.

Have monitored with scanner that reads 'live data' to determine the fault in throttle control system.

This car's throttle is cable controlled and therefore has no throttle control system. There are too many possibilities to guess at without being able to see the car, fuel system, ignition, mechanical fault.... Check engine light on while driving? Does it always have low power? Is the idle smooth?
TPS is electrical. ........
