Could anyone tell me what some of the symptoms of a bad Thottle Position Sensor?

Poor fuel economy, hesitation, loss of power, studdering, stalling. Any or all of those.

Usually its a rolling idle, or poor throttle responce

Your symptom is very textbook "bad TPS"

I agree. You should check it's adjustment and how smooth it transcends from idle to WOT. The best method of doing the later is in ohms with a DMM that has a bargraph. If you have one, let me know and I'll walk you through it.

Take care,
