Faulty TPS Sensor?
Ok, isnt the car supposed to idle real high when the TPS is unplugged?
Because, I currently have an electrical problem with my car, dont know whats causing it, but I unplugged the sensor while the car was running, and the idle didnt change one bit, yeah the SES light came on, but no idle change.
Isnt the car supposed to idle fast with the sensor unplugged?
Is my sensor bad?

Try measuring the voltage output of the sensor in the idle position... It should be ~0.6 volts (anywhere from 0.45 to 0.65 is considered acceptable)... As you increase the throttle position, that reading should approach 5 volts smoothly (do this with the ignition on, engine off)..
Unplugging it won't change the idle..
