Check the electrical connection at the sensor. Are you using evoscan to read the tps signal? If so log with the car off and ignition on and see if the number changes as you press down and release the gas pedal. My base idle tps is 12.94 and it goes up to 99.94 or something right around there. If I increase my base to 13 my idle goes too high so it's set right where it is happy. Some people have higher, some have lower.
