Rough Idle problem.

Hi,
This thing is driving me insane. 1996 GT, obdII. Check engine light is on (TPS code). I checked the volts and the sensor seems to be ok, it goes from 0.5v closed to 3.5v fully opened.
Now my question here is when I try to set the idle speed I've read I have to jump the TEN and GND pins in the diagnostic connector... The problem is that doing so makes the engine go from the 500 rpm to 900 rpm. So no matter where I set the idle speed it will drop about 400rpm when I take the jump wire off. Is that normal? Any kind of help or comment will be greatly appreciated!

change the sensor the 3.5 voltage is to low and it really would help if you had an analog volt meter because the other thing the the tps sensor is smoothness, does it go from .5 to 4.5 smoothly if not and there is a sudden drop the sensor is bad
