If you think it could be the TPS....
I had issues with a dancing tach reading while I would be driving steady at cruising speed. When I looked for a test to check the TPS all I got was "put a new one in its place, if the issue goes away, it was the TPS". I took my TPS out an connected the leads of my old simpson analog multi-meter to the terminals of the sensor and moved it slowly back n forth. Set on high ohms, the meter showed a dead spot on the sensor, in other words, not a steady rise an fall in resistance. So with confidence, one new TPS and 2 years worth of random head scratching about the mystery, DONE.

Food for Thought.
