If you can scan the car in live data, see what the TPS and coolant temp is reading.
TPS at closed throttle should be.60 to <1.0V and at WOT should be below 5V at about 4.6 or so V.
Coolant temp should be close to thermostat regulating temp or 195 degres.
If the ECM has faulted either sensor the default value will be WOT in the case of the TPS and -40 in the case of coolant temp. Sensor.
If you have replaced the TPS, you must disconnect battery so TPS voltage at closed throttle can be reset in the ECM. The TPS should gradually go up from.6V to 4.6V as the throttle is depressed.
Failure of either sensor will cause the car to run rich.
