I don't know about you, but I distrust multimeter resistance readings. I would rather watch the voltage sweep and verify that it is linear than attempt to compute the resistive dividing ratio of the sensor (I do understand that the factory service manual lists a resistance spec, but I also know that the ECU reads voltage, not resistance).
If you like, I can try to test the TPS voltage on my bone-stock '90 GXL (which purrs like a kitten on one rotor) right now.
I know you said that the TPS was unplugged, are you absolutely sure that you disconnected all wires to the TPS and that you had a good strong connection with your multimeter leads?(contact resistance is the reason that I mistrust resistance readings).
