Rough Idle Issue

Ok, so I had just checked the resistance of the TPS and I kept getting about 7K. I followed the instructions to the T and inserted the .7mm feeler blade and loosened the screws, turned clockwise and the needle of the ohmmeter never deflected and constantly stayed at about 7K. So, am I doing something wrong or is my TPS bad? I'm sorry if I seem like an idiot, but I am trying to learn. I've done many other mechanical jobs on this car, but these sensors and electronics are new to me. Thanks again for the help. As a side note, I checked again and still only have code 21 which the car has had for the 2 months I've owned it, even after replacing the O2 sensor and pulling EFI fuse and battery to try to reset.
