I just swapped from and ls to gsr motor and moved my tps from the ls to the gsr. My voltages are .045 closed and 5.04 WOT. the check engine light only comes on if i keep the car full throttle for about 4 seconds. Why would it do this?

 

anyone?

 

Faulty TPS sensor, the signal should range from .45V closed to 4.5V WOT, having 5.04V at WOT indicates the arm inside the sensor is not touching the resistance tracks. If you hook up an OBD scan tool, your code should be one of these.
